Spectral Analysis of Signals Spectral analysis is concerned with the determination of frequency contents of a continuous-time signal ga(t)using DSP methods It involves the determination of either the energy spectrum or the power spectrum of the signal If ga(t)is sufficiently bandlimited,spectral characteristics of its discrete-time equivalent g[n]should provide a good estimate of spectral characteristics of ga(t)Spectral Analysis of Signals • Spectral analysis is concerned with the determination of frequency contents of a continuous-time signal ga(t) using DSP methods • It involves the determination of either the energy spectrum or the power spectrum of the signal • If ga(t) is sufficiently bandlimited, spectral characteristics of its discrete-time equivalent g[n] should provide a good estimate of spectral characteristics of ga(t)
