Explain the generation and detection of Pulse Amplitude Modulation (PAM).

Worked SolutionAI Assisted

Answer

PAM: Sample via FET switch (natural) or S/H (flat-top). Detection via LPF $f_s/2$ with $\text{sinc}$ equalizer. Spectrum replicated at $nf_s$ weighted $\text{sinc}$ . Applications intermediate for PCM, TDM.
