CONTAINS TWO SEPARATE AUDIO SYSTEMS - Elenco
increase the power of the audio signal received from either detector to a power level capable of driving the speaker. The audio amplifier is IC or transistor version. Section 2 includes the AM detector circuit and the AGC (automatic gain control) stage. The AM detector converts the amplitude modulated IF (intermediate frequency) signal to a low ...

classes.engineering.wustl.eduFigure 9.4: Operational amplifier connected as a voltage follower voltage follower of Figure 9.4. The input voltage is Vi,. The virtual short forces v-= v+ and, therefore, Vo = Vi. Hence, it is termed a voltage follower. Now you may be thinking that this is a circuit that serves no function since the output voltage merely equals the input voltage.
