## Re: Moving the notches of a Moving Average Filter

I have some doubts as it is possible to optimize a CIC in this way using simple and resource-saving methods. I've already made a number of attempts and developed...

## Re: Farrow Filter

Exactly, the non-matching frequencies do not automatically mean clock domain crossing. We first assume that the information is synchronized. Then a simple 50/41...

## Re: CIC bus width

More bits might be left away in case assumptions can be made regarding the utilization of the vector width - depending on the problem. Since this is related to FPGA...

## Re: The Nyquist Sampling Theorem

Being a musician and involved in music production, I wonder how many lyrics we already have in the market that have been "composed" using such automatic methods....

## Re: ChatGPT's idea of a computationally efficient digital filter - ha ha ha...

Looking forward to. According to my understanding this works mainly because of the high oversampling ration(?) - so the output is finally not exactly the same as...

## Re: Has any one seen this window function?

The point about that function is that it can effectively be integrated into DSPs and FPGAs, since one needs only N+1 calculations and can use the values twice....

## Re: Determining the frequency (between 1-100MHz) & amplitude of a sinusoid

This is a classic task for a continuous fitting operation. I once wrote a module for this task in C that uses the minimum squares of the deviations and works iteratively....

The question is, what are the 192kHz intended for. Is it to transport higher frequencies like e.g. 80kHz which a 96k signal cannot transport? You will need a ADC...

## Re: SPDIF clock recovery

I had suggested a little FPGA for this but do not know how familiar you are with that. S/PDIF is a piece of cake in there, so is clock recovery and jitter attenuation...

## Re: Digital Emulation of Tube Amps

An interesting aspect to mention is also powering, cooling and the situation how a tube is built in which has some relevance according to my investigations. Also...

## Re: Will this FPGA be suitable for DSP purposes?

Hm, such questions populate our German electronics forum 3 times a day. I'm far away from wanting to attack anyone, but on the one hand such questions don't really...

## Re: Is there a way to mathematically prove whether the convolution of a digital signal will lead to digital clipping?

Of course this is possible and often necessary. Like already mentioned the coeffs have to be investigated but also the incoming data. If for instance there is a...

## Re: Learning FPGA

For me it is funny to see, how many people now start with FPGAs, including also music euqipment manufaction who used to deny this all the time.I really wonder...
