Question 2-1811571125-Xiao Peng

Overview

The sound signal is converted into an electrical signal through the electret microphone, mixed with the local oscillator signal of the circuit, amplified by the amplifier, and then transmitted to the antenna and emitted through the antenna.
(2) The receiving antenna receives the radio signal and sends it to the receiver.
(3) The receiver converts the radio signal into the original voice, which is then played back by the loudspeaker. At this time, the original voice signal can be heard.
