In pulse position modulation, which parameter carries the message?
Answer: C
The displacement in time carries the message, with amplitude and width both held constant, so the scheme shares width modulation's noise immunity and improves on its power efficiency. The other three parameters are all fixed in this scheme. Position modulation puts everything into timing, which is why it needs accurate synchronisation and why it tolerates amplitude noise so well.
