hey, if anyone can help me i want ppm and pwm equation calculations and spectra

 

Equations relating what to what?
What aspect of spectral theory?
Google will point you to all you want to know .

I didnt find mathematical equation for pwm and ppm

I don't think you understand what those words actually mean.

Can anyone represent to me the matematical equation for pwm?

Sure
100% duty cycle is 255
0% duty cycle is 0

0% duty cycle is 0

Its not the mathematical equation

Hi,

There are a lot of equations depending on what you are doing.
Show an example, even if it is not accurate, of what you want. Then we'll know what you need.

I have pam mathematical equation i want pwm like this forme

 

How about
Duty cycle = Ton/(Ton+Toff) ?
Unless you can be more specific we can't really help.

The picture i post it didnt specify what i need ?

 

I want fourier coefficient for pwm

 

Hi,

Your picture is not drawn very clearly and you did not even capture the entire equation.
You have to be much, much more careful if you want answers.

The PWM spectra looks like a bunch of humps that grow smaller and smaller with frequency.
The magnitude of ck is:
|ck|=Vo*tau/T*abs(sin(k*wo*tau/2)/(k*wo*tau/2)), k=0,1,2,3,...
