Block Diagram Of General Feedback Amplifier. Find applications of the feedback systems. Voltage shunt feedback voltage sampling shunt mixing.

But while amplifying it just increases the strength of its input signal whether it contains informat. We have also seen that block diagrams can be used to demonstrate the various types of feedback systems. Block diagram of feedback system.

Current sampling shunt mixing current shunt feedback is present in the current amplifiers.

The figure shown below represents the block diagram of an amplifier employing feedback network. We have also seen that block diagrams can be used to demonstrate the various types of feedback systems. The various blocks of the feedback amplifier section are discussed below. By subtracting the actual output value multiplied by the feedback β from the source signal and using the subtraction result as the input to the open loop amplifier a we can accurately control the output even when the input to the output relationship is complex.
