how do i plot a sawtooth graph without using the sawtooth function?

T = 10*(1/50);

Fs = 1000;

dt = 1/Fs;

t = 0:dt:T-dt;

x = sawtooth(2*pi*50*t);

plot(t,x)

grid on

You have to define a high value for parameter 'n' in the code.

Answer 2

[Vedika Shinde]

i) Write a set of MATLAB commands for approximating the continuous-time periodic Sawtooth wave of amplitude 5 volts, fundamental frequency 20Hz,and duty cycle 0.5. Plot five cycles of this waveform. ii) Find out the fourier series of this waveform plotted in (i). (iii) Plot the equation of Fourier series to get the original waveform back.

Answer 3

[Matthias SImons]

I stumbled over this question and generated an own solution:

To generate a sawtooth with time period T, over a time signal t just use interp1:

xx = [0 T/2 T];
yy = [1 0 1];
y = interp1(xx, yy, mod(t, T));
