Extremely parallel QPM -- another one of my telecommuniations imaginations 8 31 (6/20/2008 5:45:03 AM) comp.dsp Hi: Please don't get upset at me. I am currently thinking about an extremely hypothetical form of QPM [Quantized Phase Modulation] in telecommunications technology. This too theoretical-too-be-realistic QPM... Green

QAM of the most advanced dial-up modem 1 51 (6/10/2008 4:20:48 AM) comp.dsp Hi: The most advanced dial-up modem [V.92] uses QAM [a mixture of amplitude and phase modulation]. Does this modem use more phases or more amplitudes to convey data? For the same amount of bits-per-baud, if... Green

Disadvantages of *extreme* MPSK? 12 45 (6/5/2008 6:39:45 AM) comp.dsp Hi: In the hypothetical situation I describe, dial-up modem telecommunications technology devices use extreme MPSK [Multiple Phase Shift Keying] as the modulation scheme. This too-good-to-be-true MPSK uses ... Green

Linear PCM video; specs? 1 40 (6/1/2008 5:14:36 AM) comp.dsp Hi: What are the specs of uncompressed linear PCM video? The specs of uncompressed linear PCM audio are bit-rate, sample-rate, bit-resolution, and number of channels [1 if mono, 2 if stereo] In LPCM audio, ... Green

Does an inadequate pixel-density cause spatial aliasing? 12 48 (5/25/2008 4:01:24 AM) comp.dsp Hi: Is spatial aliasing caused by an insufficient pixel-density? Also, some video websites say that spatial aliasing causes jaggies, other say it causes the Moire effect, still others say it causes pixelati... Green

QAM; 1-amplitude, many phases, 1-baud, 1 gigabit-per-baud 5 41 (5/18/2008 6:01:41 PM) comp.dsp Eric Jacobsen wrote in http://groups.google.com/group/comp.dsp/msg/dc369177d865440e : > On Sat, 17 May 2008 15:55:02 -0700, "Green Xenon [Radium]" > wrote: >> Let's say I am using QAM and want a baud-r...

Modulation scheme with multiple phases and a two amplitudes? 22 34 (5/16/2008 4:56:05 AM) comp.dsp Hi: QAM uses two carrier waves that are 90-degrees out of phases with each each and amplitude-modulates them. QAM only has two phases but can have more than two amplitude levels. Is there any modulation sche... Green

What is the analog equivalent of aliasing? 28 43 (5/13/2008 12:20:36 AM) comp.dsp Hi: Aliasing is a digital entity. What is the analog equivalent of aliasing? Thanks, Radium ... Green

What's the use of a 192 kHz sample rate? 234 94 (5/3/2008 4:41:34 AM) comp.dsp Hi: Why does DVD-Audio use 192 kHz sample rate? What's the advantage over 44.1 kHz? Humans can't hear the full range of a 192 kHz sample rate? On average, what is the minimum sample rate for a guy in his ear... Green

Is 44.1 KHz sample-rate enough to cover the entire human hearing range? 25 37 (5/3/2008 1:17:43 AM) comp.dsp They say no: http://www.allexperts.com/user.cgi?m=6&catID=835&qID=4743184 http://www.allexperts.com/user.cgi?m=6&catID=835&qID=4742942 They say Yes: http://www.allexperts.com/user.cgi?m=6&catID=835&qID=4742...

Disadvantages of using AM for DSSS/FHSS? 20 53 (4/28/2008 9:26:35 PM) comp.dsp Hi: Most cell phones and wireless internet routers, modems, and access points that use spread spectrum usually broadcast and receive their data on FM-radio waves. Just out of curiosity, I ask, why not use AM... glucegen1 (225)
