Hi Folks, following on from the series of articles on feedback controllers and applications, I am considering doing an article later in the year on Negative Latency...

## Sampling frequency of slow phenomena to obtain PSDs

Started by 2 months ago●7 replies●latest reply 2 months ago●70 viewsHello all, this is my first post.In my current project I need to obtain PSDs of temperature noise from thermocouples submerged in water at 17 ºC, in this conditions...

Hi,I’m working on radar system. We got new HW platform and we see very strong spikes in the time domain signal about 50db above the the target signal.What can...

## fixing sample rate error/mismatch

Started by 2 months ago●5 replies●latest reply 2 months ago●72 viewsHi,In my current project, I need to match two audio streams that runs on different clocks. Both claims to have 48k sample rate, but one contains an unknown small...

Hi all,Suppose I have an input signal \( x[n] \) of length \( N \), an FIR filter \( h[n] \) of length \( M \), and a window function \( w[n] \) of length \( N...

## Not understanding digital signal processing

Started by 2 months ago●18 replies●latest reply 2 months ago●183 viewsI'm learning dsp by reading Understanding digital signal processing by Richard Lyons. I'm on chapter 2, aliasing. So here's my thing. I know algebra and I know...

If I have a modulated signal A*cos(2pi*fc*t + phi), I can demodulate it using IQ demodulator and estimate the phase using I and Q channel information. When it comes...

## raised-cosine filter paramiters.

Started by 3 months ago●3 replies●latest reply 2 months ago●119 viewsI have 228000 samples of 1 second BPSK signal (with noise) which is shaped with raised-cosine pulse, rollof factor = 1. Signal data rate is 1187.5 symbols/s....
