Singularity issue due to Zero-frequency component
Started by 3 months ago●4 replies●latest reply 3 months ago●67 viewsI am a Ph.D. student working on nonlinear elastic modeling of elastic materials in the Netherlands. In my formulation, I have a singularity issue at the zero frequency...
I am often confused between PHY, L1 and Baseband processing.Are they same? if not, can anyone help with some explanation please.Thanks,
Synchronizing sampling rates between a device and an audio output

Started by Hi, Suppose I have time domain LTE signal L and time domain WiFi signal W. L is generated by taking 2048 point IFFT and W is generated by taking 64 point FFT. Power...
IIR vs FIR filtering effectiveness in voice bandwidth
Started by 3 months ago●9 replies●latest reply 3 months ago●123 viewsI recently read (somewhere) that you can get a better cutoff response by running you data through a filter multiple times. I am using cascading butterworth filters...
Forgive my newbie questions. I always thought that to down simple a signal you first should do a low pass filter and then Dow sample to prevent any aliasing. So...
Why am I getting the same frequency response plots when one has aliasing and the other does not?
Started by 3 months ago●9 replies●latest reply 3 months ago●85 viewsWhen givenx[n] = cos[2*pi*f*n]n = 0: T :10T = 1/fsfor fs = 10HzI get the same frequency response figures.for f = 3Hz, f = 7Hz, and f = 13Hz.so that means that aliasing...
