(a) A signal discretized in time domain is $[1,2,3,4,1,2,3,4, \ldots$.$] For a sampling$ frequency of 100 Hz , Plot amplitude, phase and power spectra of the sequence.

Explanation

The amplitude, phase, and power spectra of the sequence can be plotted using the given sequence. The amplitude spectrum is a periodic repetition of the sequence [1, 2, 3, 4]. The phase spectrum is a linear ramp with a slope of π/2 rad/sample. The power spectrum is a periodic repetition of the sequence [1^2, 2^2, 3^2, 4^2].
