How does the receiver process the radio signal?

The radio receiver is a device used to receive radio signals. It can convert the RF signal received by the antenna into a baseband signal. Usually, we know the frequency of RF is very high but the baseband frequency is lower, so it requires the receiver to process. According to different processing ways, radio receivers can be divided into direct-emitting radio receiver amplifiers and superheterodyne receivers.  ...
