Objectives of this experiment:
1. To construct the pulse-position and pulse width demodulation training board.
2. To show the pulse width and pulse position modulation signal is demodulated.
3. To show that the PWM demodulated output is nearly the same as the modulating frequency by using phase locked loop demodulator.
