I am using a sine wave

a = A sin(2*pi*f*t)

where A = 2.

I made a square wave by adding the odd harmonics of sine wave.

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 +......

When the square wave is created the amplitude of the square wave will not be the same as the sine wave. What will be the coefficient for the amplitude of the square wave?

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);
