Diagram Of Radio Receiver. This is the circuit diagram of mini am radio receiver. Point a has wide range of modulated radio frequency signals.
This block diagram is for a simple radio receiver such as a crystal radio and consequently it does not have an oscillator or mixer stage. The method of demodulation is totally. Two transistor radio receivers.
It is similar in principle to the zn414 radio ic which is now replaced by the mk484.
Standard broadcast for fm is 88 108 mhz. It is being amplified in lf amplifier and then led into the hf oscillator where the carrier signal is being created. Block diagram of fm receiver with explanation. In fm the operating frequencies are much higher than that in am.
