Frequency Demodulation Help

[8886032323]

Hi everyone,

I am very new to labview.. Somehow I managed to Simulate Frequency Modulation.

But now, I am facing difficulty in demodulating it. I need to implement the demodulation without using modulation tool kit. 

Help would be appreciated. 

I am attaching the Vi file which i have done. 

In order to view this we have to download triple display from the following link

u can find the download under the Labview Section .. under requirements

Thanks

Hello,

My idea for a demodulator for this system is pretty simple. If you derive the FM signal you should get a signal of varying amplitude, where the amplitude variation is the information you entered the signal(but derived once). After this you can just use a peak detector to acquire the envelope of this signal and finally reconstruct your initial signal. Be careful when you integrate to obtain your initial signal, because the signal will have an offset.

Hope this helps.
