GS&EI ElectEngg 14 2024 1601-2025 According to the Nyquist-Shannon sampling theorem, for a band-limited signal, the sampling rate ($f_s$) must be at least twice the maximum frequency component ($f_{max}$) present in the signal to allow for perfect reconstruction. The formula is $f_s \ge 2 f_{max}$.
A 4 GHz carrier is DSB-SC modulated by a low-pass message signal with maximum frequency of 2 MHz. The resultant signal is to be ideally sampled. The maximum frequency of the sampling impulse train should be
