Not understanding digital signal processing
Started by 2 weeks ago●18 replies●latest reply 1 week ago●168 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...
I 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....
I'm wondering how to decouple user data/symbol rate from a carrier clock in a Direct-RF DAC transmitter solution.I have an I+Q root raised cosine data source that...

How to efficiently control an FIR's magnitude response by altering its phase spectrum
Started by 1 month ago●21 replies●latest reply 3 weeks ago●115 viewsNote: I posted this question on Signal Processing Stack Exchange yesterday. Because the one answer I got so far was not-so-satisfying, although surely well-intentioned,...
Convolution and Fast Fourier Transforms Efficiency Gains
Started by 1 month ago●3 replies●latest reply 1 month ago●115 viewsHello,I had quite a few questions I was hoping someone could answer regarding the use of FFT's when convolving a digital signal:1. When convolving some digital signal...
Hi,A very basic question related to real to complex conversion. Let's say I have a ADC sampling at 1Gsps - real samples only. In the digital domain (FPGA), I want...
