How do you find the phase of a discrete time signal?
for each n, one can find its magnitude and phase once writing it in the polar or rectangular form where the polar form is x[n]=(e−0.1n)(ej0.3n). Then its magnitude is |x[n]|=|e−0.1n||ej0.3n|=e−0.1n and its phase is ϕ=0.3n radians for each n.
How do you calculate the phase of a signal?
Calculating Phase Shift
The phase shift equation is ps = 360 * td / p, where ps is the phase shift in degrees, td is the time difference between waves and p is the wave period. Continuing the example, 360 * -0.001 / 0.01 gives a phase shift of -36 degrees.
How do you plot a discrete time signal?
A discrete time signal just means sampling your continuous signal at discrete time intervals. The simplest way this can be done is by increasing your step in n. n = [-5:0.25:5]; y = 5*cos(pi*(n/2)-(pi/2));
