Title: group delay in low pass filter Post by ic_engr on Jun 12th, 2009, 8:47am Hello All, If I perform AC analysis for a circuit and then in ADE, Result-Direct Plot-Main form menu it provides function called GD, does this provide group delay. There is a function called 'GD' in the main form of the results, would this provide group delay. Secondly, I would like to increase the delay in my low pass filter which has a pass band of 100Hz to 8kHz. A target delay of 75mSec is required. I am open to another opamp and RC elements, but want to preserve the same BW and noise. Would this be possible. Does anyone have information on bessel filter that could do this. A schematic would be useful. ic_engr |
