Evaluate discrete-time signal, Electrical Engineering

Assignment Help:

Consider the following signals, sketch each one of them and comment on the periodic nature:

(a) x(t) = A cos(2πf0t + θ), where A, f0, and θ are the amplitude, frequency, and phase of the signal.

(b) x(t) = ej(2πf0t+θ) , A> 0.

(c) Unit step signal u-1(t) defined by u-1(t) = 1802_Evaluate Discrete-time signal.png

(d) Discrete-time signal x[n] = A cos(2πf0n + θ), where n is an integer.
