Hi,
I am designing a triangle wave generator. I am wondering how to define the linearity of it. E.g.,if it is defined 1% lineraity. How it is defined?

thanks a lot.
 

The wave form what is observed in the electronic circuits are exaponential waves, not triangular waves. If u keep the leniority of the exponential then it will look like triangle. so may be the linearity should be kept in the requested range.. check it...


regards,
Tumma.
 

chang830,

Let Vp = the peak value of the triangle.
Let Delta = the absolute value of the maximum deviation between the generated triangle wave segment and a perfect straight line from 0 to the peak value.
Linearity = (Delta/Vp) * 100.
Regards,
Kral
 

You can take the traiangular wave and then use curve fitting algorithm in MATLab. Then remove an ideal Triangular wave from it. What ever is left is non-linearity (distortion).
