I skimmed the first article and can see your points. Not sure what is "opt"-coupling; I could understand "opt *o* "-coupling much better. Furthermore, wavelength tuning... I have a hard time that just

Is There a Digital Audio Sinewave Generator That Uses Delta Modulation?
A digital audio sinewave generator that uses delta modulation is supposed to have one output only (one MCU pin, for example). It outputs a delta bits stream which, after filtering, gives a low THD

Being an old HP uW SE, the 346 A noise source is 10 MHz to 18 GHz. You get that range for a mere $4000 but it is flat! Dan Kahn

Re: transistor help needed
Need to work backwards in any design to the input requirements. How much voltage is the output being driven? What is the start-up current of the motor being driven? Now you can select the MOSFET size.

As a first approximation, driving a MOSFET's gate means driving into a big capacitance.? The bigger/stronger the FET, the bigger is that capacitance.? It can be quite large, and part of it is from
