40 years of power electronics and signal processing design experience using DSPs starting with TI's TMS32010 in 1985 (very first one, as far as I know). Ex-TI employee. Extensive experience designing with what is now called the C2000 family. Power experience from a few watts to 500 kW and pulsed power experience to 120 MJ (TJII stellerator magnetic containment field in conjunction with CERN and fully DSP controlled). 4 granted patents, 4 publications.

## Re: Matlab CIC fixed point modelling

Yeah, I play with CIC filters from time to time and Matlab requires that you purchase their fixed point add-in specifically for this filter.  The textbooks that...

## Re: Matlab CIC fixed point modelling

Dr. Mike - The CIC filter only works with fixed point math.  Everything that I've read indicates that the algorithm isn't compatible with floating point.  I suspect...

## Re: 50Hz and harmonics filtering

Are you collecting a cycle of data and then generating a response once per cycle (i.e., decimation), or are you using running algorithms that generate a new result...

## Re: 50Hz and harmonics filtering

For those of you who perhaps aren't familiar with power line harmonics, this is not a noise signal floating on top of the desired signal.  The distortions are caused...

## Re: 50Hz and harmonics filtering

You can find an algorithm that has good step response in IEEE Transactions on Industrial Electronics, Vol. 43, No. 1, 2/96, "DSP Control of High-Power UPS Systems...

## Re: 50Hz and harmonics filtering

djmaguire, assuming that you are not talking about using a shielded cable, can you provide a link to this topic?  I did not find any reference in a quick Google...

## Re: 50Hz and harmonics filtering

I've worked with this problem for many years (40+) in active control of power line current or voltage harmonics.  I am not familiar with the "shielded cable algorithm",...

## Re: Anyone Familiar With and Use Frequently ? Matlab R2018b / Excel 2016 - Analyzing Wavelets & Thresholding Coefficients

I use Excel daily - my concern was only with the 64-bit version.  I think that Richard has successfully worked around the issues with it by finding the appropriate...

## Re: Anyone Familiar With and Use Frequently ? Matlab R2018b / Excel 2016 - Analyzing Wavelets & Thresholding Coefficients

I am not familiar with the process that you are using so I can't help there, but I had a major red flag go up for using the 64-bit version of Excel.  According...
