Started as an EE many years ago, went soft(ware) several years back. Not as good a fit, since my interests have always been mathematical relations underlying it all. I'm back now, doing RADARs and steeped the calculations again.

## Re: Fractionally Spaced Equalizer

Thanks Fred, and thanks for the pptx file.  I'll read through it and see if I can push it down to my son for his project...Mitch

## Re: Fractionally Spaced Equalizer

Fred,thanks for the enlightening answer.  I feel like a beginner again.  I took BASIC DSP back in about '82.  I've not had the opportunity to use it only a few...

## Re: Fractionally Spaced Equalizer

If I'm reading correctly, you're looking for an answer to the old equalizer issues when matching to musical instruments??  If that's so, maybe look into the "constant...

## Re: Setting required FFT spectrum bandwidth w.r.t the Sampling rate

Maybe take a look at the Constant Q transform. You decide number of bins, frequencies involved, etc...  often used for music because of the specificity of frequencies...

## Re: Real-time Wavelet Transform

I don't know that this is the answer for you, more like some things to think about.  CWT (continuous wavelet transform) is "Concerned" with time as well as frequencies. ...

## Re: sum of sinusoids

Hi Sharan123,I thought I'd add one more thought to help you cement this concept.  What Rick and Cedron have already said is the way to understand it mathematically...

## Re: Xcorr versus Correlation through toeplitz matrix

I'm not quite sure that I understand your question here.  A cross correlation is a measure of the similarity of to series.  It is often referred to as a sliding...

## Re: Hermitian matrix

Let me see if I can tackle this:My first thought is, "are you taking a linear algebra class?"  If you're in the middle of a class, this won't make a lot of sense...

## Re: Hermitian matrix

I believe we should start with the definition of an Hermitian Matrix.  This is a matrix whose conjugate transpose is equal (same as) the original matrix.  OK,...
