Hi,

I have been trawling all over the Internet for the mathmatical equation for a sawtooth wave.

Can anyone help me???

 

What do you mean by "mathematical equation" - are you (for instance) referring to a time domain or frequency domain representation?

 

I have produced a sawtooth wave using a combination or even harmonics, but have been asked to provide a better representation of the wave using a simpler method. So by terms of simpler method it rules out Fourier analysis. What are you meaning by time domain or frequency domain representation?

 

It's a linear equation over one period: y = mx + b. Repeat the same way for other periods.

 

The method used to calculate the sawtooth wave from a sine wave was = Asin(BӨ)

Is there not a simple equation just for a sawtooth waveform??

 

In my previous post, I gave the exact equation for it. Are you instead desiring the Fourier expansion of a sawtooth wave? You can look that up in many math handbooks, such as page 455 of the CRC Standard Mathematical Tables, 26th edition.

You need to phrase your question in a more detailed form to get an appropriate answer.

 

You can use the MOD function:

or a similar function that returns a remainder. See the attachment.
