Work the two problems below.
Include answers for Problems and include MATLAB coding along with any output plots
that support solutions into one Word document entitled “Lab1_StudentID”. Where your
student id is substituted in the file name.
In this lab, you will create and analyze a number of continuous and discrete-time
sinusoids using MATLAB.
IMPORTANT NOTE: You must include screenshots of MATLAB coding and MATLAB
outputs in your lab submission. The screenshots MUST have the date and time stamp
from Windows that appears in the lower right corner of the screen or else the lab will be
worth 1%. See example below.
Activity 1:
Consider the discrete-time signal and assume N=12.
.
For M = 4, 5, and 10, plot xM[n] on the interval 0 ≤ n ≤ 2N-1. Use stem in MATLAB to create
your plots, and be sure to appropriately label your axes. (You can copy your plots by selecting
Edit > Copy Figure at the top of the figure pane.) Using Insert –> Arrow at the top of the figure
pane, insert an arrow to indicate the end of the first period and beginning of the next period.
Activity 2:
Consider the following two signals:
Assume N = 6 for signal x1[n]. Plot each signal separately for the interval of 0 ≤ n ≤ 24. Use
Question:
1. Are the signals periodic? Explain.
