Demodulation

[StijnMeersman]

Is there a possibility to directly demodulate a FM signal in SignalExpress?

Hello,

You can do it the following way:

- First acquire the signal

- Then rightclick and select "Analysis >> Time-Domain Measurements >>Timing and Transition"

Then double click on the created step and select the correct input. Also make sure that the frequency option is enabled in  the "Configuration and Results" tab

Normally your frequency output should now show the instantaneous frequency of the incoming signal. 

If you know the relation between your original modulating signal and the change in frequency in the modulated signal, then your problem is solved.
