DC component in wireless

[noelcucu]

what is the theory behind why there is a DC component receiver coil? when the transmitter transmits AC signal with DC component does is it also receive ac signal with dc component?

 

[hexreader]

Signal received is AC. Any DC offset is imposed by receiver circuitry

Why DC offset is imposed by the receiver circuit?

Because only AC component transmits - you cannot (physics don't allow) transmission of a DC anything.

It depends entirely on the receiver design, as DC offeset isn't likely to be a problem there's no need to get rid of it.

Is that the actual voltage? When i meausure the output of the rectifier i also got 24v.

The actual voltage of what?, and DC voltage might, or might not, have some relation to the incoming signal - again, everything depends. entirely on the design. However, 24V seems rather high for a radio receiver?.
