Instructions for Double Sideband Suppressed Carrier (DSB-SC) Modulation

Note: Use the sliders to input the message frequency, carrier frequency, and message signal gain.
Step 1: Click on the "Generate Message" button to create the input message signal based on the selected frequency and gain.
Step 2: Click on the "Generate Carrier" button to generate the carrier signal. The carrier frequency must be higher than the message frequency. You can adjust both using the sliders.
Step 3: Click on the "Generate DSB-SC Modulated Signal" button to produce the DSB-SC signal.
Step 4: Click the "Show Frequency Spectrums" button to visualize the frequency spectrum of the DSB-SC signal.
