MOONSHOT: Look, I'm not saying I know anything about FPGAs or physics engines but... Anyone in NY wanna pool some dough and try and run a physics engine at 44.1kHz through that new afterburner card? I've started projects with less knowledge. Famouse last words: How hard could it be? https://ieeexplore.ieee.org/document/8892162


Why don't we just zero out FFT bins?

This is probably a stupid question but, well, I'm not all that smart... Instead of going through all the trouble of designing complicated digital filters, why don't we just pick the frequencies that we want to supress and replace those bins in the FFT with zeros?

The Event Horizon Telescope team of course deserves a huge amount of credit for their results. But it's interesting how they got there. Here's an article with some non-technical discussion: https://fivethirtyeight.com/features/forget-the-black-hole-picture-check-out-the-sweet-technolog y-that-made-it-possible/ Their data is too noisy to actually create a black hole image. So they a

Recently I attended a coding seminar. The speaker very briefly reviewed the relevant history; first Hamming codes, ~1960: BCH codes, ~1970: convolutional, 1995: polar, 2002: LDPC Clue me in - what was the advance in each case? I worked on a BCH project once, that seemed fairly efficient, how is it, or other algorithms, deficient? -- Rich

In the 60's I spent time as a BSEE student. Took a course using _Signals, Systems and Communication_ , Lathi , 1965 A generation later I found comp.dsp and obtained a copy of _Understanding Digital Signal Processing_ , Lyons, 2004 May I answers suitable for a bright high school student who reads eclectically {will account for what I've forgotten &/or never knew ;}.

Occasionally I attend recitals, where the student performs a concerto. It's a bit of a financial stretch for the music department to hire an orchestra, so a second pianist accompanies, acting as the orchestra. Thus someone has to condense the entire orchestral section down to a single instrument! A mighty job of compression indeed. How do they do that? The conductor isn't a mat...

Hi DSP people, I have a black-box system that ingests digital images, can perform a number of transformations on it, and later spits some of them out in random order. My goal is to create an algorithm to generate digital images I sent into the system so that I can identify them when/if they come out, and tell which kind of transformations they have undergone. The images I put in have a n...

Is there any info on how to implement fft and ifft algorithms that aren't recursive? I'd like to possibly calculate a really long on inside a signal chain so attempting to compute a 2 second fft in one function call would probably be disastrous. -Matt

Hey Folks, I did some googling on this and couldn't get a satisfying answer. 1. What polarization is used to transmit? 2. What polarization is used to receive? The answer to question 2 would seem to be horizontal since that is the orientation of the antennas I've seen. But most broadcast TV antennas are (I believe) vertical. If I've got it right, then why do the tx/rx polarizati...
