Help required

00:36:02

I have a project on PWM transmission so require following circuits
1. Circuit for coversion of analog to PWM
2. Circuit for transmitting PWM wirelessly
3. Demodulating the recieved PWM to get the analog signal back.
Please help if u know anything abt any of the above circuit and post the link in comment.

Analog to pwm are most class d chips in existence. a Circuit to transmit pwm would be any FM transmitter and receiver circuit(maybe you need a license). Pwm to analog is a simple LF filter. But it would be better to transmit digitally with a commercial module and make the pwm at the receiver side with a microcontroller or something unless you really need a continuous signal in which case you need to check if it's allowed by your country.

Sorry i don't know of anyone who has done something like this before. Why do you want to transmit PWM in the first place? This seems overly complicated for any application I can think of. Can you tell me more about the reasons?
