Started by 2 years ago●5 replies●latest reply 2 years ago●170 viewsI already posted my question on stackoverflow but hopefully I can get some comments/answers from DSP experts contributing to this forum too:For regular FIR filters...
Noise floor is varying with respect to Decimation rate.
Started by 2 years ago●8 replies●latest reply 2 years ago●435 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...

How to separate these orthogonal inputs
Started by 2 years ago●12 replies●latest reply 2 years ago●277 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...
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...
