Demodulation is the process of extracting the original information signal from the modulated carrier signal. There are several demodulation methods used in analog communication systems:
Basic communication blocks, signal types, and the need for modulation. Amplitude Modulation (AM) Time/frequency domain representation, DSB-SC, SSB, and VSB. 4 Angle Modulation Frequency Modulation (FM) and Phase Modulation (PM). 5 Pulse Modulation Transitioning toward digital, covering PAM, PWM, and PPM. 6 Noise Analysis analog communication by v chandrasekhar pdf
