Re: Video filter

Passive or active?
I think active filters are better option ..
Attached is the schematic of 5-pole baseband video filter with group delay equalization ..

Re: Video filter

These opamps are pretty expencive.
What about a passive video filter?
Thanks.

Re: Video filter

This passive filter has no group delay compensation, but if you would like to have this compensation you can replace the last 3-transistor amplifier with a buffer (same as the first stage) and add the group delay compensation identical to the one from the active filter option ..
