Superheterodyne Receiver Block Diagram. The way in which the receiver works can be seen by following the signal as is passes through the receiver. The working of a superheterodyne receiver is explained with the help of the block diagram given below in Fig along with the waveforms at the output of each block.

The superheterodyne receiver uses one or more mixers and local oscillators to convert the received signal channel to another frequency band for more convenient filtering and amplification. The dotted line indicates that the local oscillator and RF filter must be tuned in tandem. This details the most basic form of the receiver and serves to illustrate the basic blocks and their function.

Converts the RF signal to IF signal. I have kept the theory very simple and at introductory level for beginners however at some point there will be another article taking it further. Superheterodyne Radio Receiver Block Diagram Here is a block diagram of a typical superheterodyne superhet radio receiver together with theory and notes explaining each block. The way in which the receiver works can be seen by following the signal as is passes through the receiver.
