Instructions for Amplitude Modulation (AM)
- Step 1: Click on 'Generate Message' button to generate input message signal
- Step 2: Then click on 'Generate Carrier' button to generate carrier signal
- Step 3: The carrier frequency has to be more than the message frequency and You can change frequencies using sliders
- Step 4: Click on 'Generate Amplitude Modulated Signal' button to generate Amplitude Modulated Signal
- Here, modulation index = Gain / DC. The frequency spectrum is shown for a modulation index of 1.
Instructions for Amplitude Demodulation
- Step 1: Tunable LPF's Cutoff frequency works in accordance with the Message frequency
- Step 2: You can Demodulate the AM Signal clicking on the 'Perform AM Demodulation' button
- Step 3: Click on the 'Show Frequency Spectrums' button to see spectrums of the message, AM modulated and demodulated signal
