Answer #1

Here is the Matlab code to plot . Copy and paste the code below in the MATLAB window and hit enter, MATLAB will give you the plot

n = -5 : 5;
y = heaviside(n-2);
stem(n, y)
axis([-10 10 -1 5])

Explanation of code

n = -5 : 5;:This line represents range of the horizontal axis time instants

y = heaviside(n-2);: This represents the shifted unit step sequence

stem(n, y): It is a command to discrete plot

axis([-10 10 -1 5]): It shows the range of horizontal and vertical axis

Thumbs me up, Please

Please use Mat lab only. Thanks (b) Plotting Sunspots Load the Matlab data file, sunspot.dat, and experiment with making plots and subplots. The file is a simple 288 row by 2 column matrix where the first column has consecutive years from 1700 until 1987 and the second column has the mean sunspot number for that year. Then we will construct year and spots vectors from the two columns and plot spots as a function of year. load sunspot.dat; year =...
