Functions of radio receiver & frequency mixer in super heterodyne receiver
Q. The functions of radio receiver are- Published on 14 Oct 15a. Receive the Incoming modulated carrier by antenna
b. Select the wanted signal and reject the unwanted signals and noise
c. Detection and amplification of the information signal from the carrier
d. All of the above
ANSWER: All of the above
The radio receivers receive the incoming modulated carrier by the receiving antennas. Then they select the wanted signal from the carrier and reject the unwanted signals and noise. The received signal is then amplified by the RF amplifiers. Detection of the information signal is done from the received carrier and the information or the modulating signal is then filtered and amplified.
