PAM (Pulse Amplitude Modulation)

  1. Generate Message Signal: Input the message frequency and square carrier pulse frequency into the provided fields. Click the button to create the message signal.
  2. Generate Carrier Signal: Click the button to produce the square pulse carrier signal.
  3. Generate PAM Signal: Click the button to produce the PAM signal.
  4. Demodulate PAM Signal: Click the button to recover the original message signal from the modulated PAM signal.
  5. Show Frequency Spectrums: Click the button to view the PAM spectrum.

PWM (Pulse Width Modulation)

  1. Generate Message Signal: Input the message frequency and square carrier pulse frequency into the provided fields. Click the button to create the message signal.
  2. Generate Carrier Signal: Click the button to produce the square pulse carrier signal.
  3. Generate PWM Signal: Click the button to produce the PWM signal.
  4. Demodulate PWM Signal: Click the button to recover the original message signal from the modulated PWM signal.

PPM (Pulse Position Modulation)

  1. Generate Message Signal: Input the message frequency, and square carrier pulse frequency into the provided fields. Click the button to create the message signal.
  2. Generate PPM Signal: Click the button to produce the PPM signal.
  3. Demodulate PPM Signal: Click the button to recover the original message signal from the modulated PPM signal.
