Signals The Basics Exercises

Consider the signal depicted below.

Select all the true statements.

Consider the signal depicted below.

The … indicates that the pattern continues outside the interval shown.

Select all the correct statements.

Consider the signal $x[n] = \sin^2(\pi n/5)$. Select the true statement.

A signal is given by $y[n] =\cos^2(\pi n/6)$. Find the fundamental period of $y[n]$.

Consider the signal $x(t)$ depicted below.

Use the MATLAB code CTSinusoids.m to generate a graph of a sinusoid

$x(t) = 4\cos(2\pi 0.5 t +\pi/4)$

on $0 \le t \le 10$ and find the fundamental period.
