Help needed with matlab code. Sawtooth wave.
显示 更早的评论
Here is a code, which calculates square wave frequency and phase spectrum. What I should change to make it plot sawtooth wave?
clc, clear
t=-3:1e-3:3;
tau=1;
T=2*tau;
U=1;
N=10;
K=0:N
k0=0
Sk1=(2*U)*(sin(K*pi/T))./(K*pi)
Sk1(1)=0.5
figure(1)
subplot(211)
stem(K, abs(Sk1))
subplot(212)
stem(K, phase(Sk1))
S=Sk1(1)
for K=1:N
S = S + abs(Sk1(K+1))*cos(K*pi*t+phase(Sk1(K+1))…
end
figure(2)
plot(t,S), grid

Please format your code as explained in the "Markup help" link on this page. I've done this for you this time.

What is the difference, in amplitude and phase, between a square wave and a sawtooth wave? Where are the phase and amplitude set in your code?
