It's been a few months since the launch of the new forums.  Here are a few thoughts. The thumbsup and beer buttons    If there is one thing that could have a...

I created a simple FMCW sweep using MATLAB in baseband, BW = 100MHz:sweepTime = 1e-3; % 1 ms sweep BW = 1e8; %100 MHz; fs = 2e8;% 200 MHz sample rate % FMCW waveform:...

Assuming my DAC is 1 million samples per second 12-bit, with the goal of increasing the effective number of bits beyond 12 bit at the expense of reduced sample...

I needed to determine the 3 and 6 dB points of the Goertzel algorithm. While I found many posts here that addressed bandwidth indirectly, they didn’t specifically...

I have a single frequency (100kHz) magnetic wave (known power) signal measured by three, orthogonally sensitive, placed sensors (coils in x,y,z direction). The...

The OFDM receiver front end operates on a real signal from the antenna. The receiver's IQMixer both downconverts the received signal to baseband and transforms the...

In the IEEE 1902.2 narrow-band OFDM PLC standard, the IFFT is performed but only the real parts are taken for the transmission while discarding the imaginary parts...

Hello DSPrelated community,I'm developing an interactive web application for learning DSP concepts as part of a university project (project overview: https://thierrydutoit.github.io/iDSP/)....

Hi all! My first post here! Long time lurker first time poster. This one is kinda specifically directed at @RickLyons but happy for anyone to answer. I am reading: https://www.researchgate.net/publication/352874961......

When performing an FFT, modifying the magnitude spectrum in some arbitrary way, and then applying an inverse FFT, how should I handle circular convolution? How can...
