Phase Shift Keying Mod and Dmod using an Op Amp Schmitt Trigger

This is revised from the old simulator due to constant "no solution" coming up.

Phase Shift Key (known as PSK) is one of the method used in digital wireless. The phase of the carrier wave is modulated while the frequency and amplitude stay the same .
The bottom area is the modulator circuit and the top area is the demodulator.  

1 bit = out of phase
0 bit = in phase

demo looks nice, but im not so sure whats happen if we take any amplitude information out of the antenna (transport layer) with a limiter. PSK can be seen as AM you multiply with +-1 and get a simple phase shift of 180°
