Hi,

I ve got a triangular wave having some DC content..can someone tell me how to remove this dc content so that my triangular wave starts from 0V.

Can you tell me how to design it properly??

If you connect series capasitor to triangular wave , you get +/- symmetrical wave to gnd.
If you need wave from zero to +Vpp, you must make bias circuit for adjusting offset -Vpp to gnd.

use a diffrential amplifier
The dc output would be eliminated and only triangular waveform would be observed at the output
have a look at these sites**broken link removed**

If you assume that the output impedance of the source of the signal is negligible low, you need to find out the input impedance of the load (or the next stage) ..
Once you determine it you can calculate the value of the coupling capacitor in the terms of 3dB frequency, or just use the web-available calculator:
Coupling Capacitor Calculator by V-Cap
