Question

Generate a sawtooth waveform using a matlab code. Frequency of sawtooth wave is 50Hz. Peak peak amplitude is 2V. Using subplot window, plot the Saw tooth waveform and the folded saw tooth waveform Show the code and plots.

Answer 1

T = 5*(1/50); % Sawtooth waveform for 5 cycle
Fs = 500; %sampling frequency
ts = 1/Fs; %sampling period
t = 0:ts:T-ts;
x=sawtooth(2*pi*50*t);
x = (x+1);
subplot(2,1,1);
plot(t,x);
xlabel ('Time');
ylabel ('Amplitude');
title ('Sawtooth Waveform');
grid on
subplot(2,1,2);
plot(-t,x);
xlabel ('Time');
ylabel ('Amplitude');
title (' Folded Sawtooth Waveform');
grid on
