functionMATLABmatlab function

Hello

As attached the square wave equation.

How can I plot it ?

Best Answer

Try this:

f = 5;                                                                      % Frequency
N = 16;                                                                     % Order Of Harmonics
t = linspace(0, 4, 500);                                                    % Time Vector
sqwv = @(f,t,n) 4*sum(bsxfun(@rdivide, sin(2*pi*(1:2:N)'*t), (1:2:N)'))/pi;
figure
plot(t, sqwv(f,t,N))
grid

RESOLUTION = 1000;   %whatever is appropriate
DUTYCYCLE = 0.73;    %e.g. 73% on, 27% off
NUMBEROFCYCLES = 18;  %as appropriate
basepulse = ones(1,RESOLUTION);
squarepulse = basepulse;
squarepulse(floor(DUTYCYCLE * RESOLUTION) + 1 : end) = 0;
wavetrain = repmat(squarepulse, 1, NUMBEROFCYCLES);

What I have seen that, you b is look like as following-

A=2; f=3;
t=0:.01:10;
a=A*sin(2*pi*f*t);
%figure, plot(t,a);
b=A*sin(2*pi*f*t) + A*sin(3*2*pi*f*t)/3+A*sin(5*2*pi*f*t)/5+A*sin(7*2*pi*f*t)/7;
%[pks,locs]=findpeaks(b);
%findpeaks(b)
plot(t,b);
