What is the primary function of a radio receiver?

The main idea is that a radio receiver’s job is to recover the original information carried by the radio waves by amplifying and extracting it from the carrier. It begins by tuning and filtering to select the desired frequency, then amplifies the weak RF signal, and finally demodulates it to recover the baseband information, which is presented as audible sound or as a data signal. Modulation is the process of encoding information onto a carrier, which is done by the transmitter, not the receiver. Transmitting, storing for later decoding, or modulating are not the primary functions of a receiver; they relate to other parts of the radio system or to different operations the device might perform in special cases, but the core purpose here is to convert the received RF signal into usable audio or data.
