Unfortunately, as Figures 6-14 and 6-19 both show, even weak signals do not escape this reduction. Power System II | Block diagram of single area AGC AGC HW Block Diagram - Free download as PDF File (. Figure 1 is a general block diagram for an AGC loop. FM Receiver Block Diagram: The FM receiver is a superheterodyne receiver, and the FM Receiver Block Diagram of Figure 6-28 shows just how similar it is to an AM receiver. The AGC block adjusts the signal to achieve a desired power level of 1 W. It was Figure 4. 1 [5] shows block diagram representation of an isolated power system represented by an equivalent inertia M, load damping constant D, turbine and governing system with an effective speed droop There are two approaches to implement an AGC.
