Generating Dual Sine Waves with Different Frequencies and Amplitudes

Generate two sine wave signals with distinct frequencies and amplitudes, superimpose them, perform spectral analysis, and reconstruct the original signals using a low-pass filter (LPF)

Envelope Demodulation Algorithm

This algorithm implements two distinct methods for envelope demodulation: the first approach applies Hilbert transform followed by FFT analysis, while the second method squares the signal before passing it through a low-pass filter (LPF) and performing FFT.
