Question

How do you create a sawtooth wave in MATLAB?

a) 'saw_wave()' function
b) 'plot_sawtooth()' command
c) 'sawtooth()' function
d) 'generate_wave(sawtooth)' command

Answer 1

To create a sawtooth wave in MATLAB, the correct function to use is 'sawtooth()' which is part of the Signal Processing Toolbox. The function helps generate a customizable sawtooth wave that can be plotted with a specified frequency and the number of points in each period.

Step-by-step explanation:

To create a sawtooth wave in MATLAB, you would use the 'sawtooth()' function. This function is part of the Signal Processing Toolbox in MATLAB, and it generates a sawtooth wave with a specified frequency and length. You can customize the sawtooth wave by specifying the number of points in one period of the wave and the width of the wave.

Here's an example of how to generate a sawtooth wave using MATLAB's 'sawtooth()' function:

T = 1; fs = 1000; t = 0:1/fs:T-1/fs; f = 5; w = sawtooth(2 × pi × f × t); plot(t,w); title('Sawtooth Wave')

In this example, we first define the period T, sampling frequency fs, time vector t, and the frequency of the wave f. We then use the 'sawtooth()' function to generate the wave and plot it using MATLAB's 'plot()' function. The resulting graph will show a sawtooth wave over one period T at the frequency f.
