Question: Consider the following analog sinusoidal signal: ???????? (????) = 3 sin 100???????? (a) Sketch the signal ????????(????) for 0 < ???? < 30 ms. (b)

Consider the following analog sinusoidal signal: ???????? (????) = 3 sin 100???????? (a) Sketch the signal ????????(????) for 0 < ???? < 30 ms. (b) The signal ????????(????) is sampled with a sampling rate ???????? = 300 samples/s. Determine the frequency of the discrete-time signal ????(????) = ????????(????????), ???? = 1 /???????? and show that it is periodic. (c) Compute the sample values in one period of ????(????). Sketch ????(????) on the same diagram with ????????(????). What is the period of the discrete-time signal in milliseconds?
