Help to generate periodic triangular pulse and vary its duty cycle.

Hi guys, I am trying to generate a periodic triangular pulse Ac, with a frequency of 2khz and an amplitude of 8, i am also struggling to find a way to vary the cycle.

This is my script:

f = 2000;
T = 10*(1/f);
Fs = 4*f;
t = 0:1/Fs:T-1/Fs;
x = 8*sawtooth(2*pi*400*t);
plot(t,x)

Thanks in advance.

hello

your code generates a 400 sawtooth signal , not a 2 kHz triangular wave

I made a few mods in your code to get the correct result

f_signal = 2000;
periods = 10;
T = periods*(1/f_signal);
Fs = 4*f_signal;
dt = 1/Fs;
t = 0:dt:T-dt;
x = 8*sawtooth(2*pi*f_signal*t,0.5);
plot(t,x)

what do you mean by "vary the cycle" ? are you referring to the width parameter of sawtooth function ?

Hi @Mathieu NOE, thanks for your reply, ahh, I see, you are right.

Although the exercise asks me to show only one pulse and vary the duty cycle in percentage.Although the exercise asks me to show only one pulse and vary the duty cycle in percentage.
