And yet, the clueless Troll Doe has continued to post incorrectly formatted USENET articles that are devoid of content (latest example on Sat, 18 Jun 2022 12:53:36 GMT in message-id <kVjrK.298018$3%%8.92995@usenetxs.com>). NOBODY likes the John Doe troll's contentless spam. This posting is a public service announcement for any google groups readers who happen by to point out that John Dope does not even follow the rules it uses to troll other posters. QIMDPZ0HUYw9

The power supply dynamics (voltage regulation, current limiting, output impedance, slew rates) will be done in an FPGA. The FPGA reads ADCs and generates PWM into the output fets. The ADCs are ADUM7703, an isolated delta-sigma thing. It makes essentially a 1-wire random noisy duty cycle whose average value tells the input voltage. It needs to be decimated, digitally lowpass filtered, in the FPGA, and we have choices. We can get 160 KHz bandwidth at 15 bits effective a/d resolution, or 20 bits at about 50 KHz, both overkill for a power supply. They are $6 each, which isn't a big deal here. Three ADCs isn't complex, it's actually simple. If the customer doesn't elect to enable remote sense, they get a free high-res DVM. Either way they can verify the actual voltage at the load. They do high-value tests (like blowing blades off jet engines to test containment) and want to be sure everything works. I've noticed that some engineers will go to great lengths, and add a lot of complexity, to save trivial parts cost. Like building a fancy charge-pump power supply just because they can, instead of buying a $3 dc/dc converter, to cite one fictitious example. -- Anybody can count to one. - Robert Widlar

You idiots have mostly ruined usenet with your endless hen-clucking. Your are either bots, or have astounding boredom tolerance. Of course you can't design electronics; your personalities are all wrong. -- Anybody can count to one. - Robert Widlar
Eddie, the Astraweb nym-shifting stalker is flagging off-topic posts 
with its forgery of my ID, then replies to its own forgery. Strange but true.

Eddie has never posted anything NORMAL except when it got a spanking...

Here, John Larkin appears to be confusing me with the forger of my ID. 

The fact nym-shifting trolls can so easily dupe regular USENET posters is
one reason I started pointing out header information. 

Some people are still not cognizant enough to get it...

There is a distinct possibility "Edward Hernandez" would've made it into this group (coming from the electronics repair group where it was jilted) even if not for me, similar to how "Bertrand Sindri" appeared around the same timeframe (also coming from the electronics repair group) for no apparent reason. Obviously I have nothing to do with that troll now flagging what it sees as off-topic, while copying my ID to do so. Some regulars here like Bozo and Ricksy have encouraged it, and it's gotten worse. The trolling "Edward Hernandez" does here most certainly isn't my fault.

He wouldn't do it if John Doe weren't posting here. Since John Doe posts absolutely nothing of any value at all, we'd all be very grateful if he went away, along with all the people who feel the need to point out that he is an obnoxious half-wit without having anything else to offer. -- Bill Sloman, Sydney

+1, and I'd add the need for constant attention seeking. Severe mental disorder. J
No point in discussing anything with Bill "Bozo" Sloman, the Australian 
troll. Bozo is an incessant liar who cannot be reasoned with. Its fiction 
never ends.

"the user has posted under the same name in other places, so not
nym-shifting" (Bozo sucks at logic) 

"the Mueller investigation was about Trump only because Trump made it so"
(Bozo being Bozo) 

"the concepts "male" and "female" are essentially social constructions"
(Bozo is a textbook cannibal leftist)
