*Veesion 1.5* Changing frequency will result in proportional change in Red current level.
Wait for a while for red line to be stable!!!!
The AND gate output is dependent upon the phase difference between the two signals, i.e. it acts as a phase detector and produces a voltage output that is proportional to the phase difference and hence to the level of deviation on the signal.

With Better Modulation Index. Changing the frequency will increase or decrease the max peaks at the output of and gate.
Wait for a minute before you start :p
Increase in frequency-> higher peaks
Decrease-> Lower peaks.
This way this demodulator can extract info from FM Signals to speaker recognizable format.
