The analog output is connected to a low-pass filter, which filters out high-frequency aliases when the Amiga is using a lower sampling rate ( see Nyquist limit ).

One idea that has drawn attention for several decades is that consciousness is associated with high-frequency ( gamma band ) oscillations in brain activity.

The Metal Gear Solid series of video games has a recurring character known as Grey Fox or the " Cyborg Ninja " who is a person wearing a cybernetic exoskeleton ( either worn as a suit or grafted directly to the character's body ) and wielding a high-frequency blade.

Examples of FTL proposals are changing the " frequency " of mass to a higher state by applying high-frequency waves of energy, the Alcubierre drive, and the traversable wormhole, although the physical plausibility of some of these solutions is uncertain.

Self-insurance is usually used to pay for high-frequency, low-severity losses.

" Jaggies " is the informal name for artifacts in raster images, most frequently from aliasing, which in turn is often caused by non-linear mixing effects producing high-frequency components or missing or poor anti-aliasing filtering prior to sampling.

In electronics and telecommunications, modulation is the process of varying one or more properties of a high-frequency periodic waveform, called the carrier signal, with a modulating signal which typically contains information to be transmitted.

Typically a high-frequency sinusoid waveform is used as carrier signal, but a square wave pulse train may also be used.

Some studies have related the use of quinine and hearing impairment, particularly high-frequency loss, but it has not been conclusively established whether such impairment is temporary or permanent.

* High-power, high-frequency operation, such as that used in over-the-air television broadcasting, is better achieved in vacuum tubes due to improved electron mobility in a vacuum.

AC bias is the addition of an inaudible high-frequency signal ( generally from 40 to 150 kHz ) to the audio signal.

This buzzing is particularly familiar from low-frequency ( 50 Hz or 60 Hz ) mains hum, and high-frequency ( 15, 734 Hz ( NTSC ) or 15, 625 Hz ( PAL )) CRT noise.

However, for many high-frequency applications, proximity effect is more severe than skin effect, and in some limited cases, simple stranded wire can reduce proximity effect.

Typically, the new, high-frequency copy is referred to as the " RF " ( radio-frequency ) signal.

Delay encoding is used primarily for encoding radio signals because the frequency spectrum of the encoded signal contains less low-frequency energy than a conventional non-return-to-zero ( NRZ ) signal and less high-frequency energy than a biphase signal.

The underlying technology of transport across DSL facilities uses high-frequency sinusoidal carrier wave modulation, which is an analog signal transmission.

Note: Frequency frogging is accomplished by having modulators, which are integrated into specially designed repeaters, translate a low-frequency group to a high-frequency group, and vice versa.

In telecommunication and radio science, an ionospheric sounding is a technique that provides real-time data on high-frequency ionospheric-dependent radio propagation, using a basic system consisting of a synchronized transmitter and receiver.

In adaptive high-frequency ( HF ) radio, link quality analysis ( LQA ) is the overall process by which measurements of signal quality are made, assessed, and analyzed.

Pseudo bit error ratio ( PBER ) in adaptive high-frequency ( HF ) radio, is a bit error ratio derived by a majority decoder that processes redundant transmissions.

The high-frequency resistance is inversely proportional to the DC bias current through the diode.

This high-frequency resistance may vary over a wide range ( from 0. 1 ohm to 10 kΩ in some cases ; the useful range is smaller, though ).

A pulsed high voltage source ( typically 1-2 kV ) is generated and applied to the specimen, with pulse repetition rates in the hundreds of kilohertz range.

An excellent method for the measurement of self-diffusion coefficients is pulsed field gradient ( PFG ) NMR, where no isotopic tracers are needed.

In PEF processing, a substance is placed between two electrodes, then the pulsed electric field is applied.

A laser can be classified as operating in either continuous or pulsed mode, depending on whether the power output is essentially continuous over time or whether its output takes the form of pulses of light on one or another time scale.

When the modulation rate is on time scales much slower than the cavity lifetime and the time period over which energy can be stored in the lasing medium or pumping mechanism, then it is still classified as a " modulated " or " pulsed " continuous wave laser.

Another method of achieving pulsed laser operation is to pump the laser material with a source that is itself pulsed, either through electronic charging in the case of flash lamps, or another laser which is already pulsed.

Its reaction to silicon is " plasmaless ", is purely chemical and spontaneous and is often operated in pulsed mode.

In pulsed applications there is a delay of several cycles before the oscillator achieves full peak power, and the build-up of anode voltage must be coordinated with the build-up of oscillator output.

Radboud University runs the High Field Magnetic Laboratory which is able to achieve some of the highest fields available in Europe at 33 teslas ( continuous ) and 60 teslas ( pulsed ).

This nonlinearity is typically only observed at very high light intensities ( values of the electric field comparable to interatomic electric fields, typically 10 < sup > 8 </ sup > V / m ) such as those provided by pulsed lasers.

However, stellarators, unlike tokamaks, do not require a toroidal current, so that the expense and complexity of current drive and / or the loss of availability and periodic stresses of pulsed operation can be avoided, and there is no risk of toroidal current disruptions.

This is inherently a pulsed process because there is a limit to the current through the primary ( there are also other limitations on long pulses ).

In addition to the authentication and acknowledgment procedures which precede and follow the sending of the go messages, again in special codes, each message also contains an `` internal authenticator '', another specific signal to convince the recipient that he is getting the real thing.

By this standard, it is determined that where two stations operating on the same frequency are involved, objectionable interference from station A exists at any point within the service area of station B where station A's signal is of an intensity one-twentieth or more of the strength of station B's signal at that point.

For this reason, the more uncertain skywave service was denominated `` secondary '' in our rules, as compared to the steadier, more reliable groundwave `` primary service '', and, for both skywave service and skywave interference, signal strength is expressed in terms of percentage of time a particular signal-intensity level is exceeded -- 50 percent of the time for skywave service, 10 percent of the time for skywave interference.

The design of a mechanical interlocking frame is much like a mechanical puzzle, but once understood, the principles can be applied to any track and signal arrangement.

If the lever is pulled to clear a signal or move a switch, the tappet moves a short distance lengthwise at the same time.

By this scheme, pulling one signal to clear locks all the other switch and signal levers in safe positions until the first signal is again restored to normal.

As an engineer approaches the plant the position of the home signal is seen in advance when he passes the `` distant '' signal located beyond the limits of the interlocking plant.

In some low-speed situations, the distant signal is fixed at caution.

The video signal is amplified and then switched, in synchronism with the three ultraviolet light sources which are sequenced by the rotating mirror so that during one-twentieth of a second only one wavelength, corresponding to red, green, or blue, is seen.

The electrical signal from the autocollimator is amplified and supplied to the Z-gyro torquer.

Essentially, the stator or reference portion of the pickoff is established with respect to the true heading direction, and the platform is turned either manually or automatically until the angular electrical pickoff signal is reduced to zero.

`` The pattern '', says Dr. Morton Schillinger, psychologist at New York's Lincoln Institute for Psychotherapy, `` is for the husband to hover about anxiously and eagerly, virtually trembling in his hope that she will flash him the signal that tonight is the night ''.

I said `` Darn it, that's the automatic signal that shows when the ignition key is on.

As soon as that one man is appointed by himself or the others or by a signal from Spencer, we are going to be rushed.
