DSP - how to remove mean. How to add a delayed signal?ckshivaram says... Dear all,I have a few questions on DSP that I would like to get of my chest. Please consider a 1-bit digital output of a sigma delta modulator as an example. 1)How can I digitally remove any dc (mean) components in the 1-bit stream? 2)I also would like to delay the output by N samples (N is quite large) and then add to its un-delayed version. What would be an efficient way to implement this? Thanks for any feedback. Navid T says... You need a digital filter a guess. Do you hve problems creating it?ecnbom says... What kind of filter would I need that elimintates the dc term but won't distrub the signal close to dc? A differentiator won't do. Is there not a different way without using a filter?thanks, |
