Radio Block Diagram. In fm the operating frequencies are much higher than that in am. Block diagram of radio in order to better understand the way the radio transmitter works block diagram of a simple am amplitude modulated signal transmitter is shown on pic.
Smart radios the positive control over the transmitters use of the spectrum has traditionally been the purview of the radio operators who were guided and trained to follow the rules of. In some analog processing is required. Then this signal is amplified in rf amplifier stage.
Fm radio block diagram 14.
The main application of the rf module is an embedded system to communicate with another device wirelessly. The next block is audio pre amplifier. A block diagram representing various stages of a basic continuous wave radio transmitter. Following the clock signal flow we see the master clock is 24756mhz the accuracy of this master clock determines the pilot frequency which must be 19khz 1hz.
