Gain controlled by command amplifier circuit is shown in the graph below.In phase lock return circuit,gain controlled by logic amplifier is needed . It consists of four comparators and a transistor . When the input instructions are high level, the gain Au is 1. When the input instructions is low level, the gain Au is 2. The bandwidth at full power which is 10Vp - p is 10KHz.
