iPod Shuffle[edit]

I believe this DSP is used in the iPod Shuffle. —Preceding unsigned comment added by 65.92.44.209 (talk • contribs)

Yep, it is embedded in the STMP3xxx system-on-a-chip series. -- intgr ^#%@! 22:25, 31 May 2007 (UTC)[reply]

ADSL filters[edit]

Any reference for that ADSL 20-bit filter topic ?— Preceding unsigned comment added by 196.202.2.206 (talk • contribs) 2007 (UTC)

20-bit filter arithmetic is quite plausible for ADSL. This is based on the typical width of the input from the ADC^[1] and the well-known fact that many filter algorithms need an accuracy larger than the data by a few bits. I'll remove the citation-needed tag. --Rainald62 (talk) 16:48, 7 December 2016 (UTC)[reply]

^ [1], quote from p. 7: "Starr, Cioffi and Silverman [19, p. 299] recommend using 14-bit ADC, while ADSL transceivers commonly use 16-bit ADCs. Fixed-point DSPs commonly use more than 16-bit fixed-point arithmetic."

Silly[edit]

Sorry, but the "by whom" flagging of "The leftmost four bits are considered [by whom?] ample headroom for calculations" is as silly as flagging "the majority of human beings are right-handed." Anyone reading this article - even a nearly complete N00B to analog and digital processes - should know this.
