Description : In a microwave test bench, why is the microwave signal amplitude modulated at 1 kHz? (1) To increase the sensitivity of measurement (2) To transmit the signal to a far-off place (3) To study amplitude modulation (4) Because crystal detector fails at microwave frequencies
Last Answer : In a microwave test bench, why is the microwave signal amplitude modulated at 1 kHz? Because crystal detector fails at microwave frequencies
