Okay, so if I understand you correctly, you are looking for an all-pass filter in magnitude, with a fixed group delay over some range of frequencies?Because a constant...
I think you're over-complicating this in your head. You can do this with a large fixed delay line. Just apply a delay of fs * T samples, where T is your delay in...
Check the values for your index for x[n].In the FIR filter it looks like x is getting indexed backwards, which is why it doesn't match the convolution. Also, in...
I've found formulas in a number of places stated in different ways, but pg 8 in this pdf has it stated pretty simply:https://www.silabs.com/documents/public/application-notes/an118.pdfAs...
I'm also feeling a bit confused here. What do you mean by "filter sampling frequency," and how can it be higher than the input frequency of the ADC? I think there...
Okay, so redoing the math with that:ENOB = IW + 0.5 * log(0.5 * FS / BW) / log(2) [bits]ENOB = 8 + 0.5 * log(0.5 * 30 MHz / 20 kHz) / log(2) [bits]ENOB = 8 + 4.78 [bits]ENOB...
Probably the best description for this is "Linear System Identification," and you will find lots of solutions to this particular question.Here's a frequency domain...
Based on your other post and your information here I agree with AlanTipper that you're getting basically the expected improvement from oversampling. You are currently...
To elaborate on the suggestion of derverberation as a research topic.Dereverberation isn't a new topic, the general problem is just under-determined and so there...
