Mike, In particular I was referring to the reflection seismology community. I find it very grating that the EE community doesn't properly credit Wiener and his "yellow peril". Big oil was the only

Agree, Dave. 73 – Mike Mike B. Feher, N4FS 89 Arnold Blvd. Howell NJ 07731 908-902-3831 Sent: Sunday, July 7, 2024 6:39 AM To: [email protected] Subject: Re: [qex] Some questions on digital

Nice reply, Reg, thanks. I was just wondering since you were talking about all sorts of processing that you said “we” were doing back in the 50’s and the 60’s. So, by “we” you meant

LoL :-) No, Mike, I'm only 71. I have a large library and a lifelong habit of reading the original papers and monographs, e.g. Shannon, Weiner et al. I've discovered quite a few citations which

Wow, Reg, you must be a lot older than I am (79). I started working on DSP stuff in the late 60’s and I was only in my early 20’s then. My career spans 50 years of working on signal processing,

In the days of pure analog data acquisition, Texas Instruments was the instrument manufacturing subsidiary of Geophysical Services Inc. GSI's sole peer was Western Geophysical Inc. TI developed the

A website that hosts PDFs. My google query was (with the inner quotes): “digital signal processing "frerking" pdf” Without the inner quotes google thinks you mean “freaking”. Hope this

I always considered Frerking to be the king of communications signal processing but the books are currently out of sight. I realized his ALC in SHARC code and it ended up in a couple radios. Might

Reg, Did you do any work with Texas Instruments or their equipment? In the early 1980's one of our managers visited TI in Dallas. They showed him what he described as a "Supercomputer", using ECL

A lot of papers have been written and ink spilled over misapprehension as to what group delay means. Lots of press about "signals arriving before they were sent." They'll say anything these days to

The book I used in school was "Analog and Digital Filters:? Design and Realization", by Harry Y-F. Lam.? The last three chapters introduce the z-transform and then discuss the design and realization

See my earlier comment about the definition of the Fourier transform and the impulse response.

At which point the oil industry had been doing digital processing of seismic data for years as we could live with 4 ms sample rates. Our peak signal was at best 30-35 Hz. Still is as the earth is the

Dan, I'm not looking for simple, I'm looking for meticulously correct. I have a small book, "A Handbook of Fourier Theorems" by Champeney which I *always* consult when I am working on the fringes.

Be happy I left out the list of books by Robinson, et al. And the 2D image processing monographs of which I have a large number.
