Charge Coupling on the Cheap

[Zilch]

Charge-Coupling: What does it do?

There appears no conclusive study on the subject supported by reseach and science.

However, it would seem that turning on the voltage potential does something. As to exactly what that will take some figuring and a more intensive analysis than I really have time for at the moment.

I believe it's zero-crossing.

So long as the peak-to-peak voltage of the signal is less than 18V, the charge on the "plates" never reverses.

Think of it as Class A operation of capacitors....

I agree, Zilch. Only thing is, where are you getting 18Volts?

Battery biases at 9V.

Signal is AC.

It'd take an 18V P-P signal to drive the cap tiepoint to 0V.

That's plenty loud for compression drivers....

40.5 peak W across 8 ohms, 20.24 W RMS, no?

Been wanting to do this for months:

'Scope on bias connection of biased NL200t3 crossover, main HF cap(s).

Playing pink noise 85 dB @ 2 M.

2 V/div vertical, 2 ms/div horizontal.

Bottom of screen is -1V.

Zero crossing'd be middle of bottom major division.

Swings @ 9V +/- 2V, according to design.

That'd be 2 Watts peak into 8 Ohms at this point. 6 dB of attenuation after that, tho.

[SEE, we DID have LEDs back in the olden days, and they're still runnin' today.... ]
