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

The resultant electrical signal can then be electronically amplified.

Electronic stethoscopes require conversion of acoustic sound waves to electrical signals which can then be amplified and processed for optimal listening.

Most string instruments can be fitted with piezoelectric or magnetic pickups to convert the string's vibrations into an electrical signal that is amplified and then converted back into sound by loudspeakers.

** Loudspeaker, earphone – converts electrical signals into sound ( amplified signal → magnetic field → motion → air pressure )

These alpha waves are amplified and the resulting electrical signal is used to vibrate percussion instruments distributed around the performance space.

Specific examples include: electrical motors, pneumatic actuators, hydraulic actuators, linear actuators, comb drive, piezoelectric actuators and amplified piezoelectric actuators, thermal bimorphs, micromirror devices and electroactive polymers.

It converts mechanical vibrational energy from a stylus riding in a spiral record groove into an electrical signal that is subsequently amplified and then converted back to sound by a loudspeaker system.

A pickup device is a transducer that captures mechanical vibrations, usually from suitably equipped stringed instruments such as the electric guitar, electric bass guitar, Chapman Stick, or electric violin, and converts them to an electrical signal that is amplified, recorded, or broadcast.

When an amplified signal is applied to the conductors, the resultant electrical forces react with the magnetic field to excite the Mylar film sheet, which projects sound as a dipole.

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 concept of the feedback loop to control the dynamic behavior of the system: this is negative feedback, because the sensed value is subtracted from the desired value to create the error signal, which is amplified by the controller.

Class AB is widely considered a good compromise for audio amplifiers, since much of the time the music is quiet enough that the signal stays in the " class A " region, where it is amplified with good fidelity, and by definition if passing out of this region, is large enough that the distortion products typical of class B are relatively small.

The frequency of the output pulses is typically ten or more times the highest frequency in the input signal to be amplified.

The resulting filtered signal is then an amplified replica of the input.

The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is amplified before sending it to a loudspeaker.

In electric guitars, transducers known as pickups convert string vibration to an electric signal, which in turn is amplified and fed to speakers, which vibrate the air to produce the sounds we hear.

This signal is then amplified, rectified, filtered and fed into the op-amp's non-inverting input.

In either step, the signal can be amplified.

The signal from the antenna is filtered sufficiently at least to reject the image frequency ( see below ) and possibly amplified.

The IF signal is itself filtered and amplified and possibly processed in additional ways.

The signal from the antenna is tuned and may be amplified in a so-called radio frequency ( RF ) amplifier, although this stage is often omitted.

The received signal is now processed by the demodulator stage where the audio signal ( or other baseband signal ) is recovered and then further amplified.

The resulting audio signal ( for instance ) is then amplified and drives a loudspeaker.

The alternating current signal produced by the flow of this charge is amplified and used as an analogue for the DC voltage applied to the capacitor.

The capture effect is defined as the complete suppression of the weaker signal at the receiver limiter ( if it has one ) where the weaker signal is not amplified, but attenuated.

However since the diode is a one-port ( two terminal ) device, a nonreciprocal component is needed to separate the outgoing amplified signal from the incoming input signal.

Here, all the components of the input signal are not amplified with the same phase shift, hence causing some parts of the output signal to be out of phase with the rest of the output.

In the system shown in Fig. 7-1, the accelerometer output is amplified and the resulting voltage is applied to the gyro output-axis torquer.

The platform actually tilts off level so that the accelerometer output, when amplified by Af, will supply the correct current to the gyro torquer to cancel the gyro drift.

Also, as Hall voltage is often on the order of millivolts, the output from this type of sensor cannot be used to directly drive actuators but instead must be amplified by a transistor-based circuit.

Another advantage of operating the DFA in the gain saturation region is that small fluctuations in the input signal power are reduced in the output amplified signal: smaller input signal powers experience larger ( less saturated ) gain, while larger input powers see less gain.

A small current leaving the base is amplified in the collector output.

This produces a weak rotating magnetic field that is picked up by a ( sometimes separate ) inductor, amplified electronically, and fed to a digital frequency counter whose output is typically scaled and displayed directly as field strength or output as digital data.

This ensures that an analog output is an accurate representation of an input, typically with higher amplitude ( amplified ).

If a microphone picks up the amplified sound output of loudspeakers in the same circuit, then howling and screeching sounds of audio feedback ( at up to the maximum power capacity of the amplifier ) will be heard, as random noise is re-amplified by positive feedback and filtered by the characteristics of the audio system and the room.

Musical signal content above the high-pass part of the crossover filter is sent to the main output which is amplified by the sound system.

The later vacuum triodes allowed the signal to be amplified to any desired level, typically by feeding the amplified output of from triode into the grid of the next, eventually providing more than enough power to drive a full-sized speaker.

The filter's output is amplified and rectified, creating a DC voltage whenever the desired tone is present.

To ensure that the output of the beamlines is uniform, the initial laser light is amplified from a single source in the Injection Laser System ( ILS ).

This signal was read and amplified, processed and sent to the driver tubes, a pair of 6146 power pentode output tubes.

# Signal DETECTION ( and interpretation ) system: A system of deciphering the amplified signal into an interpretable output that can be quantitative or qualitative.

This difference is amplified by the op amp and fed to the base of output transistor Q < sub > 2 </ sub >.

This signal is amplified and output is sent into the axon via the current electrode.

Its output signal is amplified and drives the other coil, which amplifies the string vibrations.

The clear box circumvented the handset mute by providing the phreak with another microphone, whose output is amplified and fed into an induction coil.

In its simplest form, Covox received 8-bit, mono signal through the parallel port and produced analog output that could be amplified and played back on loudspeakers.
