Thanks, Dan.  Yeah, it didn't make sense to me.  Not that I'm a DSP expert, mind you.  Mostly my background is RF and microwave comms, but good to know DSP as...

Late to the party, I know.  But I'm not understanding the X axis in the center plots in transient's and djmaguire's posts on April 24, 2020.  If h(n) is the impulse...

Great question and great answers!  Yes, I'm about a month and a half behind in reading up on these DSP Related questions.
I assume you have a legitimate copy of Simulink.  If so, this may be a question for the folks at MathWorks.  It is possible that their DDC and/or DUC models are...

Interesting problem/challenge!  I'm surprised to see this on DSP Related, though.  I suppose one could build an electromechanical device whereby one could steer...
FWIW, I'm a hardware guy, and these days with Global Navigation Satellite Systems (GNSS, the most familiar probably being Global Positioning System, GPS) so common...
Oh, a veritable gold mine!  Interestingly enough, Matt Donadio, author of the Tips and Tricks article on sharpening filters (really cool trick!) worked together...

I second weetabixharry's take on LabVIEW; we have a large amount of LabVIEW code here at Raytheon, and it is a nightmare to maintain.  I wasn't even aware that...
Great, all of them!  High levels of musicianship, spot-on STEM lyrics, and a sense of humor!  How can you go wrong?  Lots of fun!  Thanks for posting these!

To some degree I agree with you, StephaneB, but even more it sounds like Emerson, Lake, and Palmer (RIP, Greg Lake).  I'd swear that was Keith Emerson playing the...

Yes, nicely done!  I do have some reservations about LabView, however.  At the last two companies I have worked for, Broadcom and Raytheon, people were trying...

LOL re: MacArthur sub-genius grant!  Too bad there's not such a thing!  Probably many of us on this forum would apply. :)
Don't forget that cost is a nonlinear function of sampling frequency as well. I don't know what the exponent is, but it's definitely >1.

Probably what we will end up doing is using the AD9361's FIR filters when the desired BW is a reasonable fraction of the sample rate and bypass them and use the...

Hi.  I'm using the Matlab Filter Wizard app to design receive and transmit filters for the Analog Devices AD9361 transceiver chip.  A couple of questions that...
Up until late last year, I worked at Broadcom Ltd, so I ran into this issue.  Most of the time separate front ends.  I'm less familiar with ZigBee than BT and...
