The tuned circuit, which allows the user of a radio to filter out all but a single station, is just one example of such a circuit.

* In an LC oscillator circuit, the filter is a tuned circuit ( often called a tank circuit ) consisting of an inductor ( L ) and capacitor ( C ) connected together.

Charge flows back and forth between the capacitor's plates through the inductor, so the tuned circuit can store electrical energy oscillating at its resonant frequency.

Crystal oscillators often use the same circuits as LC oscillators, with the crystal replacing the tuned circuit ; the Pierce oscillator circuit is commonly used.

Thomson's oscillator placed an LC tuned circuit in parallel with the arc, used metal electrodes, and included a magnetic blowout.

He attached an LC circuit to the electrodes of an arc lamp, and the negative resistance of the arc excited audio frequency oscillations in the tuned circuit at its resonant frequency.

The input signal is used to switch the active device causing pulses of current to flow through a tuned circuit forming part of the load.

The diagram shows a waveform from a simple class-C circuit without the tuned load.

The tuned circuit resonates at one frequency, the fixed carrier frequency, and so the unwanted frequencies are suppressed, and the wanted full signal ( sine wave ) will be extracted by the tuned load.

The signal bandwidth of the amplifier is limited by the Q-factor of the tuned circuit but this is not a serious limitation.

The average voltage at the drain is then equal to the supply voltage, and the signal voltage appearing across the tuned circuit varies from near zero to near twice the supply voltage during the rf cycle.

At a high enough frequency this capacitance can resonate with the inductance of the coil forming a tuned circuit, causing the coil to become self-resonant.

When inserted together with a galvanometer, into a tuned electrical circuit, it could be used as a very sensitive rectifying detector of high frequency wireless currents, known as radio waves.

His major contributions were the introduction of a closed tuned circuit in the generating part of the transmitter, and its separation from the radiating part ( the antenna ) by means of inductive coupling, and later on the usage of crystals for receiving purposes.

The stages of an intermediate frequency amplifier are tuned to a particular frequency not dependent on the receiving frequency ; it greatly simplifies optimization of the circuit.

To produce higher frequencies, manufacturers make overtone crystals tuned to put the 3rd, 5th, or 7th overtone at the desired frequency, because they are thicker and therefore easier to manufacture than a fundamental crystal that would produce the same frequency — although getting the desired overtone frequency requires a slightly more complicated oscillator circuit.

The intent was to develop an alternative receiver circuit that required fewer tuned circuits than the superheterodyne receiver.

Thus, a high Q tuned circuit in a radio receiver would be more difficult to tune, but would have greater selectivity, it would do a better job of filtering out signals from other stations that lie nearby on the spectrum.

This is typically done via a resonator – in its simplest form, a circuit with a capacitor and an inductor forming a tuned circuit.

One benefit is that the statistical moment calculations can be carried out to arbitrary accuracy such that the computations can be tuned to the precision of, e. g., the data storage format or the original measurement hardware.

Here a musical signal is tuned to the correct pitch using digital signal processing techniques.

Another feature to make LS AAS element-specific is modulation of the primary radiation and the use of a selective amplifier that is tuned to the same modulation frequency, as already postulated by Alan Walsh.

The criteria for being charged with " caught stealing " were fine tuned in 1979, with a runner being charged with being caught if he is put out while trying to steal, oversliding a base ( otherwise successfully stolen ), or is picked off a base, and tries to advance to the next base.

The four-string bass — by far the most common — is usually tuned the same as the double bass, which corresponds to pitches one octave lower than the four lower strings of a guitar ( E, A, D, and G ).

The most common solo instrument is the prima, which is tuned E-E-A ( thus the two lower strings are tuned to the same pitch ).

Sometimes the balalaika is tuned " guitar style " by folk musicians to G-B-D ( mimicking the three highest strings of the Russian guitar ), whereby it is easier to play for Russian guitar players, although classically trained balalaika purists avoid this tuning.

As the guitar is tuned to one octave below that of the violin, the same size gut could be used for the 1st strings of both instruments.

The cello ( ; plural cellos or celli ) is a bowed string instrument with four strings tuned in perfect fifths.

For real-time, it is appropriate to simplify one or more common approximations, and tune to the exact parameters of the scenery in question, which is also tuned to the agreed parameters to get the most ' bang for the buck '.

Viewership peaked on Christmas Day 1987 when an average of 28. 5 million viewers tuned in to see Hilda Ogden leave the street to start a new life as a housekeeper for long term friend Dr Lowther ( although there is some confusion as to whether or not this was actually the highest rating episode due to a special omnibus repeat of that week's episodes being combined with the original airing ).

There is usually a " resonance head " on the underside of the drum, these are usually tuned to a slightly lower pitch than the top drumhead.

Similarly, the tabla is tuned by hammering a disc held in place around the drum by ropes stretching from the top to bottom head.

A relational normalised database imposes a heavy access load over physical storage of data even if it is well tuned for high performance.

The double bass, also called the string bass, upright bass, bass fiddle, bass violin, doghouse bass, contrabass, bass viol, stand-up bass or bull fiddle, is the largest and lowest-pitched bowed string instrument in the modern symphony orchestra, with strings usually tuned to E1, A1, D2 and G2 ( see standard tuning ).

The double bass is the only modern bowed string instrument that is tuned in fourths ( like a viol ), rather than fifths ( see Tuning, below ).

Occasionally, a higher string is added instead, tuned to the C above the G string.

Greek boys and girls also go for rock-and-roll, and the stations most tuned to are those carrying United States overseas programs.

It can also be tuned to E-A-D, like its cousin, the domra, to make it easier for those trained on the domra to play the instrument, and still have a balalaika sound.

Crystals have very high Q-factor and also better temperature stability than tuned circuits, so crystal oscillators have much better frequency stability than LC or RC oscillators.

In most cases, they have both blow and draw of the same tone, though the No. 7 is blow only, and the No. 261, also blow only, has two reeds per hole, tuned an octave apart ( all these designations refer to products of M. Hohner ).

He was also the Host of the 230th July 4, 2006 of the PBS July 4 " A Capitol Fourth " Celebrations in Washington, D. C. in which he sang, danced, and played tuned drums.

There is also a piece composed by Brother Grégoire for three koras differently tuned played by one musician.

This would not only allow these services to be more easily worked on, but also separated the kernel code to allow it to be finely tuned without worrying about unintended side effects.

In the 1941 novel Sixth Column ( also known as The Day After Tomorrow ), a white resistance movement in the United States defends itself against an invasion by an Asian fascist state ( the " Pan-Asians ") using a " super-science " technology that allows ray weapons to be tuned to specific races.

For early domestic radios, tuned radio frequency receivers (" TRF "), also called the Neutrodyne, were more popular because they were cheaper, easier for a non-technical owner to use, and less costly to operate.

However, if f < small >< sub > LO </ sub ></ small > is set to f < small >< sub > d </ sub ></ small > + f < small >< sub > IF </ sub ></ small >, then an incoming radio signal at f < small >< sub > LO </ sub ></ small > + f < small >< sub > IF </ sub ></ small > will also produce a heterodyne at f < small >< sub > IF </ sub ></ small >; this is called the image frequency and must be rejected by the tuned circuits in the RF stage.

A fixed IF also allows the use of a crystal filter or similar technologies which cannot be tuned.

Some radio-frequency transformers also have movable cores ( sometimes called ' slugs ') which allow adjustment of the coupling coefficient ( and bandwidth ) of tuned radio-frequency circuits.

Here Adobe provided hand tuned bitmaps to cover the small screen fonts, and ugly scaling of any other size on the screen was also provided.

However, since neurons in V1 are also tuned to the direction and speed of motion, these early results left open the question of precisely what MT could do that V1 could not.

Occasionally the ' C ' string may also be tuned up to D.

As servers are usually administered by qualified engineers, their operating systems are also more tuned for stability and performance than for user friendliness and ease of use, Linux taking noticeably larger percentage than for desktop computers.

The reaction rate can be also tuned with particle sizes ; coarser particles burn slower than finer particles.

Marr often tuned his guitar up a full step to F-sharp to accommodate Morrissey's vocal range, and also used open tunings.

** Piccolo trumpet ( may also be tuned to A )

In German, a carillon is also called a Glockenspiel ; while in French, the true glockenspiel ( a percussion instrument consisting of a set of tuned metal bars ) is often called a carillon.

" Poorly tuned bells often give this impression and also can be out of tune with themselves.

The album had a cool, calculated feel, with clear techno and electro roots, but also showed hints of the rhythmic flourishes and tuned percussion that would later become an important feature of their work.

While hospitalized, he also developed a lifelong love and understanding of classical music through the gift of a radio, which he kept tuned to WQXR.
