- Watch video entitled “Module 1 – Introduction to MATLAB”
- Download and review the Matlab supplement on plotting signals.
- 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.
- Upload file “Lab1_StudentID”.
- In this lab, you will create and analyze a number of continuous and discrete-time sinusoids using MATLAB.
Activity 1:
Consider the discrete-time signal and assumen 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 stem and label your axes.
Question:
- Are the signals periodic? Explain.
