I have a signal that is composed of a sinusoid. I will send it over the air through radios. Part of the signal will go through processing on a computer, which means that it will be converted from analog to digital, and back again.
I have two questions. How can I model any frequency shift that will occur in this system? And, how can I model how the time of the signal may change? That is, if the signal occurs in bursts (e.g. 200 ms of tone followed by 100 ms of absence of tone), how can I determine how the time may decrease? Is the time changed only by the digital part of the system (due to sampling), or might the radio path also affect the duration?
