Noise floor is varying with respect to Decimation rate.
Started by 7 months ago●8 replies●latest reply 7 months ago●237 viewsHi all,I'm simulating 65 MHz RF data and sampled that sinewave with 120MHz fs. Passed that signal with two stage decimation filter. My final stage filter output...
Hello,I am sampling, at 192 Khz each channel, a radio signal with a IQ mixer and 2 ADC's. I combine the values into complex numbers. Literature tells that using...
My major: 3rd year at college as EE My interests: analog electronics (sensors), signals and systems (controls, DSP, wordle etc.) Now I have the option of taking...
Started by Hi all,In the 3GPP standard 38.215 Section 5.1.19, there is a reference to the definition of the RSRP for SRS.It appears to simply be the average of the power in...
Python (numpy) to Matlab/Octave conversion problem
Started by 7 months ago●4 replies●latest reply 7 months ago●129 viewsI'm new to python language. I can't figure out what happens here in code:def evaluate(self, x):
p1 = 1
p2 = np.zeros((1, self.r), dtype=self.dtype)

How to separate these orthogonal inputs
Started by 8 months ago●12 replies●latest reply 7 months ago●142 viewsHi All,A receiver of ofdm separates orthogonal tones by using fft. No problem.But there are some other signals that are also deemed orthogonal yet they are at same...
Clarity on Bit Reversal Sorting
Started by 8 months ago●5 replies●latest reply 8 months ago●121 viewsHello all,I'm going through The Scientist and Engineer's Guide to Digital Signal Processing. I'm currently on Chapter 12 - Fast Fourier Transform.I understand the...
Hello! I am new to DSP and I want to have a board which will have my audio software effect. It will be something like a spectral compressor/limiter and I will experiment...

Started by 8 months ago●3 replies●latest reply 8 months ago●177 viewsMost of you probably are well familiar with Digilent.com's website and the really cool educational products they offer. This morning, my email subscription to their...
Applications for a new FFT algorithm
Started by 9 months ago●17 replies●latest reply 9 months ago●304 viewsI have invented a new FFT algorithm I'm calling the Lifted Fourier Transform (LFT) ("lifted" because the guts of the method operate in a higher dimension than is...
