Will the circuit shown below do the receiving and show its output in the serial monitor to get the exact timings?
No, the filter on the output will ensure that you don't get any changes more rapid than 320mS.
You need two things:-
1) the modulation frequency
2) the period of the modulated pulses
Remove that capacitor to get signal 1
Replace that capacitor with a smaller one for signal 2
However you are much better off simply looking at the signal on the output of the detector with an oscilloscope. If you haven't got one then use your arduino as one, there are plenty of examples of doing this on the net.
