Block Amp Diagram. As you see in the above figure there are four blocks. Provides the input impedance very high.
As you see in the above figure there are four blocks. Voltage amplifier circuit and power amplifier circuit. We can vary the carrier signal by using r1 r2 and c.
Small signal transistor q1 and its associated components form the voltage amplification stage.
Authorized on semiconductor distributor. As you see in the above figure there are four blocks. Initially there are two type of amplifier circuit diagram is in practical ie. A dual potmeter allows you to connect both the left and right channels on one potentiometer.
