A transceiver circuit composed of a transmitter, receiver, antenna, and diodes is shown in Figure 3 below. The operation of the transceiver includes idle, transmitting, and receiving cycles. When idle, the transmitter has a leakage voltage of around 1V. During transmit, the output voltage is around 10 V. Receiver is always in operation to detect returning signals that average about 200 mV. The receiver is a sensitive device. The device can be damaged if exposed to a voltage greater than 2 V. Analyze the operation of diodes in idle, transmitting, and receiving cycle and suggest the function of the diodes in the circuit. Vy = 0.7 for all diodes
