Instructions for Frequency Modulation (FM) Step 1: Click on 'Generate Message' button to generate input message signal Step 2: Then click on 'Generate Carrier' button to generate carrier signal. The carrier frequency has to be more than the message frequency and You can change frequencies using sliders Step 3: Click on 'Generate Frequency Modulated Signal' button to generate Frequency Modulated Signal Step 4: Click the 'Show Frequency Spectrums' button to view the FM spectra. Here, β represents the frequency modulation index, given by β = kf*Am/fm​​, where Am​ is the amplitude of the message signal (assumed to be fixed), fm​ is its frequency, and kf​ is the frequency sensitivity 1 Hz Step 1: Generate Message 10 Hz ...
