## Re: About timing recovery

Adding some information on top of what kaz has said.The early-late method provides an error signal that indicates if you are in advance or delayed in relation to...

## Re: Error correcting codes

Yes,I would add that Block codes can be linear, systematic and cyclic. I don't know if non-linear block code are used in practice.

## Re: Automatic Frequency Correction AFC in DSP

To reduce the computation intensity, I would first do the symbol time recovery using a feedback strategy, because they are usually less computationally intense...

## Re: DC Blocking unexpected results

The y axe is in logarithm scale. A logarithm function returns a negative value for a lower than 1 input. If you compute the logarithm of a negative number you will...

## Re: Does group delay only match real filter delay ONLY inside the passband?

Forgive me if I am saying things you already known. Group delay is not constant for IIR filter. It is a function of the frequency. Therefore, your filter will produce...

## Re: Inverse Fourier transform and discrete time fourier series

The Discrete Fourier Transform (DFT) term is an overloaded term, as it can be a transform applied to periodic sampled signals, or a transform applied to time limited...

## Re: Downsampling from 2.0 MHz to 192kHz

If you prototype your code using MatLab, see resample and upfirdn functions help for a quickly implementation a fractional decimation.Marcelo

## Re: Zero-Padding as scalloping loss attenuator

I always think on data flow graph, because I am more used to RTL design than software design. That is why I called mixed-radix, I can not avoid to see the radix-5...

## Re: Zero-Padding as scalloping loss attenuator

Thank you Jos!This is exactly what I was looking for.Now the procedure to compute the scalloping loss for any combination of window and zero padding is clear...

## Re: Zero-Padding as scalloping loss attenuator

Hi Lyons,I am aware that i can use a mixed radix fft algorithm, but i'm going to implement this solution in an FPGA, and the FFT IP that I have is for power of 2...

## Zero-Padding as scalloping loss attenuator

Hello, I am working in a signal detector system, based on DFT, that has as input N=1280 samples from a signal where multiple tones may be present. In order to...
