Positive Feedback Amplifier Block Diagram. The block diagram of the current shunt feedback amplifier is shown below by which it is apparent that the feedback circuit is located in shunt by means of the output as well as the input. Figure 31 1 basic block diagram to illustrate the feedback concept.

For the time being consider the transfer function of positive feedback control system is. The major concerning factors of a feedback system include sensing controlling and actuating the process inside the system. The figure here shows the block diagram of the control system with feedback.

The equation of gain of the feedback amplifier with positive feedback is given by a f frac a 1 a beta these are the standard equations to calculate the gain of feedback amplifiers.

Majorly electronics circuits like amplifiers oscillators etc. We will however discuss methods for minimizing the effects of positive. Find applications of the feedback systems. For the time being consider the transfer function of positive feedback control system is.
