Hi, for reference: http://www.onsemi.com/pub_link/Collateral/MC1496-D.PDF Can I run this chip with an 80MHz carrier? I'm trying, but the output is very weak. The datasheet isn't clear to me. thanks!


AM electromagnetic waves: 20 KHz modulation frequency on an astronomically-low carrier frequency

Hi: Please don't be annoyed/offended by my question as I decreased the modulation frequency to where it would actually be realistic. I have a very weird question about electromagnetic radiation, carriers, and modulators. Is it mathematically-possible to carry a modulator signal [in this case, a pure-sine-wave-tone] with a frequency of 20 KHz and an amplitude of 1-watt-per-meter-square...

What would happen if you soldered an NTC Inrush Current Limiter to the positive terminal of your cordless drill DC motor, in series with the lead coming from the pulse width modulator (PWM) trigger speed control? Would that make the drill response laggy? Does the resistance change time vary much? What is that attribute called? Thanks.


75332P MOSFET drain connected to which battery terminal?

I have a 75332P MOSFET on a cordless drill controller heatsink. I guess it's part of a pulse width modulator. The drain (flange) connects directly to one of the battery terminals. Does the MOSFET drain go directly to the battery minus/ground terminal? Or does it go to the battery plus terminal? Thanks. -- My application... I'm desperately trying to develop a better inline ...
