Kaz,I concede that I may not have been adhering to strict definitions and terminology. Both Wannamaker ([1]) and Widrow et al. ([2]) define a quantizer as the familiar...
Kaz,    > We are a bit out of sync. I am not suggesting adding any dc      offset.I am confused: what “dc offset” are you referring to?    >...
swirhun,I took a look at Figure 13.65(b) and the signs involved in the quantization feedback are correct. As shown it implements a noise transfer function $$Y(z)/Q(z)...
Kaz, First of all, thank you for responding so promptly to my query. To be clear, my comments are on (re)quantization in a DSP signal path, e.g., the 32-bit to...
Hey kaz,You may no longer be interested in discussing this aged thread, but I wanted to write and ask you for more clarification on your comments.I do not see any...
Hi jbrower,Exactly! I'd seen several instances (including Rick's recent forum post) about some artistic endeavor such as writing lyrics, but I wanted to present...
fred,Thanks for that paper! I was reviewing an older forum post on this problem which mentioned Rick's "DSP Tips and Tricks" paper in the March 2009 issue of IEEE...
Hi Rick,Interesting experiment! I did not think to actually check out that impulse response. Robie may have a vacuum tube (or two) out..--Randy
Hi fred,These are all excellent questions on the parameters of the problem which of course you'd have to answer in a real-world scenario. Are you implying that,...
Hi Kenneth,That was my first reaction, too. It seems like that would be an obvious choice. --Randy

What is LMCW?
Design a computationally efficient digital filter which can extract a 1 kHz signal between 1000 Hz and 2000 Hz from a digital input signal with a sample rate of...

...but it's wrong. Look at verse 2. Data samples at Fs > 2*BW will be just fine ("true").

How about this? \( e^{i\pi}+1 = \) \(F(\omega) = \frac{1}{2\pi} \int_{-\infty}^{+\infty} f(t) e^{-j\omega t}\ dt\)

Dr. Mike! Long time no see (since the 2003 comp.dsp conference)! How are you man?

I wonder if any of these conjectures/strange properties are related to the fact that pi is "transcendental?"

Hey Rick,I know HRTF stands for "Head-Related Transfer Function". It is basically the transfer function of the ear as a function of the sound source's azimuth in...
