The following complex-valued signal is a phasor:

where θ[n] is the phase.

(a) When the phase changes by a constant amount versus n, the phasor rotates at a constant speed. For the following phasor:

Z[n] = ej(0.08πn – 0.25π)

make a plot of the phasor locations for n = 0, 1, 2, 7, 10, 17, 20, 33, 50, and 99.

(b) What is the period of z[n]?

(c) Repeat for the complex phasor that corresponds to the following chirp signal:

In this case, plot the phasor locations for n = 0, 1, 2, 3, 4, and 7.
