Instructions for Pulse Position Modulation (PPM)
- Step 1: Click on 'Generate Message' button to generate the input message signal
- Step 2: Then click on 'Generate PPM Pulse Train' button to generate the PPM Pulse Train signal
- Step 3: You can change the message and Sampling signal frequencies from the input fields. The sampling frequency has to be much higher than the message frequency.
- Step 4: Here, ppm Width Fraction is a fraction of the total interval, and Samples Per Pulse is the total number of samples that span one pulse interval. Pulse Width = round(ppm Width Fraction × Samples Per Pulse) (all in the terms of the number of samples)
- Step 5: Click on 'Generate PPM Signal' button to generate Pulse Width Modulated (PPM) Signal
Instructions for Pulse Position Demodulation
- Step 1: To demodulate a Pulse Position Modulated (PPM) signal, a reference pulse generator creates a timing pulse train, which is used to synchronize with the PPM signal. An RS flip-flop ensures accurate pulse generation, while a PWM demodulator measures the width of the PPM pulses and converts this width into a corresponding signal representing the original message
- Step 2: You can demodulate the PPM Signal by clicking on the 'Demodulate PPM Signal' button
