feedback path

Besides the above negative feedback path, there is an equally important positive feedback process.

Volume is controlled by RV3 in the feedback path.

The black lines are the feedback paths.

This is because the phase shift of the small reactances in the feedback path, which increases with frequency, only become significant at high frequencies.

Division is carried out with a multiplier in the feedback path of an Operational Amplifier.

This indicates there is an unwanted feedback path through the circuit from output to input of an amplifying stage.

Consider a simple feedback system with controller , plant and transfer function in the feedback path.

In some solid-state or vacuum electron devices there is sufficient internal capacitance to provide a feedback path.

One uniqueness of this whistle compared to the others described is that the length of the feedback path can be chosen arbitrarily.

The oscillator is commonly tuned to a specific frequency by varying the reactant of the feedback path within the circuit.

Range changes are achieved by changing both the feedback path to the sense winding and the amplification of the signal outside the feedback loop.

This reduces the voltage across the inductor and is represented by the feedback path -(R + R).

This estimate is then used to implement a neutralizing electronic feedback path that suppresses the tonal feedback signal.

This is an essential feature to diminish feedback paths in hearing aids and assure better intelligibility in noisy-environment communication.

This feedback path may be acoustic, through the air, or it may be mechanically coupled, for example in a telephone handset.

It is shown that quantizing systems without feedback respond to the use of particular spectrally-shaped dither signals quite differently from those with feedback paths.

Feedback paths coupled through the secondary of the output transformer reduce distortion because they compensate for the transformer's distortion to some extent.

Logic circuits without memory cells or feedback paths are called combinational, their outputs values depend only on the current value of their input values.

One problem for amplifier designers who use negative feedback is that some of the components of the circuit will introduce phase shift in the feedback path.

Fig. 5 shows the bode plot of a transimpedance amplifier that has a compensation capacitor in the feedback path, as shown in Fig. 3.

This usually means that they are less complex for a given selectivity, but the feedback paths both reduce the bandwidth available and introduce the possibility of oscillations, or ringing.

Instability in the boundary layer leads to perturbations that increase in size until a feedback path is established whereby specific frequencies of the resonance chamber are emphasized.

Hewlett used an incandescent bulb as a power detector, low pass filter and gain control element in the oscillator feedback path to control the output amplitude.

A non-integer multiple of the reference frequency can also be created by replacing the simple divide-by-N counter in the feedback path with a programmable pulse swallowing counter.

Cavities can be separated into shallow or deep ones, the difference being that for deep cavities a Class III (acoustical) feedback path may be controlling.
