115. The diagram in Fig. 8C9 shows a simplified RADAR mixer circuit using a crystal diode as the first detector. What is the output of the circuit when no echoes are being received?
Without an echo signal, the mixer lacks a second frequency to produce an intermediate frequency (IF) output. Therefore, no output is developed.
