See attached file for full description:
Consider the discrete-time signal: x[n] = sin(2*pi*Mn/N), and assume N = 12. For M = 4, 5, and 10, plot x[n] on the interval 0 =< 0 < = 2n - 1. Use stem in Matlab to create your plots, and be sure to approximately label your axes.
Questions: What is the fundamental period of each signal?
Consider the following two signals:
x1[n] = cos(2*pi*n/N) + 2cos(3*pi*n/N)
x2[n] = cos(pi * n^2/2),
And assume N = 6 for signal x1[n]. Plot each signal separately for the interval of 0 =< n < = 24. Use stem and label your axes.
Questions: are the signals periodic? Explain.
Consider the following continuous signal:
x(t) = 10exp(-3t)u(t)
Plot the continuous-time signal over the range -1=<t <= 5.
