master, slave

I'll have a box that generates waveforms. I'd like to connect it to other, identical boxes, but have one be the controlling frequency and phase-zero reference. Master and Slave is the usual terminology. Like MOSI and MISO, and master-slave flipflop, and such.

These are maybe out of fashion, but are still good terms. I can't think of a pair of words that describes these boxes as well.

Leader and Follower sound kind of lame.

Silly idea. If you need a lot of phase-locked outputs, get them all from separate direct digital synthesis chips all working from the same master frequency reference.

Analog Devices sell (non-cheap) dual and quad output devices aimed at exactly this market.

You can phase-lock any number of voltage-controlled oscillators to a particular reference frequency, but if the reference frequency changes there's going to be a lag before all the slaved outputs pull in.

Floyd M. Gardner's "Phaselock Techniques" goes into that in some detail.

AD9959 is 4 channels and you can lock as many together as you like. You can even do precisely coordinated sweeps over frequency, amplitude or phase.

Not that I agree with John L politically, however I too don't think it is incorrect to use the term Master/Slave. Virtually every culture in the world knows what it means and understands the relationship.

It would be like getting rid of Male/Female when describing connections, again we all know what they mean and it saves longer explanations.

Each box has a DDS sine generator inside an FPGA, driving a serial quad DAC to make local polyphase waveforms. That part is routine. I have plans for coordinating the frequency and phase of multiple boxes. I was wondering if there were other names for the boxes.

I'm thinking that the Dems don't dare impeach him. The trial in the Senate would be out of their control and way too hazardous.

Or, maybe they don't dare NOT impeach him. He was trying to bend foreign aid to a nation at war, in order to toss a relative of a Democrat under the bus.

What other 'hazard' matters? Republican party membership is no protection against that "bus", we've seen.

I think they may be in trouble. Their best bet may be to lose the impeachment call in the House by a few votes.

A Senate trial would go after the Bidens, and a lot of others, hard. Trump says that he WANTS that trial.

Except, of course, that he didn't.

SO, being a politician is a get out of jail free card? It certainly worked for Felonia von Pantsuit.

You've seen a mockery of "justice".

Not an allowable element of an impeachment, since 'the Bidens' aren't subject to judgment, nor did they witnes the events under consideration.

So, 'in your dreams' seems to be the appropriate sentiment.

Allowable? The Senators can call witnesses just like the House members can.

More creative/selective snipping.

Except, of course, you are full of shit, again. He did exactly that. Notice the word try, you illiterate f*ck. The mere fact that he spent our money sending folks over there to enact his retarded agenda should be imprisonable.

What the retarded bastard wanted was an announcement. It did not matter if there really was an investigation. The mere announcment would sway voters here.

You are truly pathetic to support his behavior.

And yes, you stupid twit, he DID halt the security support AFTER it was approved, and the OMB records will show it was him too.

THAT stupid move cost lives and further aided Putin's terrorist actions.

Hell, the asswipe should go to prison for the smear campaign against Yovanovitch.

I thought that Stephen Colbert did a great skit with Pompeo wantin' to go home.

The entire administration is corrupt. And a whole bunch of republicans threw their honor out the door to stand behind the dangerous buffoon.

You never had any to throw out. You are just one (another) dirt dumb f*****ad to have voted for and continually back the criminal asshole.

As usual, krw acting as dumb as dogshit.

The mockery was that of the republican party members that pulled their stupid buffoonery in order to back a stupid, dangerous buffoon. Every one that failed to appear should be jailed for it.

It's not immediately clear that the "secondary"-widget follows the "primary"-widget and isn't just some kind of back-up.
