Noise floor is varying with respect to Decimation rate.

Hi 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...
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

I'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

Hi 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

Hello 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...
Good article on Frequency warping and using the bilinear transform

Most 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

I 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...
