Answers to Common Questions
A digital representation of analog signal that shows the magnitude of the signal being sampled at random times throughout the interval is called pulse code modulation.
One analog to digital conversion method is called pulse amplitude modulation or PAM. This technique takes an analog signal, samples it and generates a series of pulse based on the results of the sampling. The term sampling means measuring t...

Pulse width modulated flow control involves switching the spray gun on and off repeatedly at a controlled rate, called the modulating frequency. The modulating frequency is the number of times the gun is switched on in one second, and is me...

PWM is not a "switch" that you buy. I don't know why you have rejected circuits utilising a 555 timer, that's quite a reasonable device to derive the on/ off timings needed. 1/4 and 1/2 seconds are very slow switching times, why...

You could get VB to generate PWM - since you are driving a heating element then the TIMER activeX control could output a waveform that is high and low, say over 1/10th of a second. You set the interval of the timer to the number of millisec...

After constructing and using my previous Pulse-Width Modulator , I decided to build the future modulators using current-modulation techniques. The reason was that the "current sink" circuit used is very easy to construct and offer...

No. Without a PWM, you are doing "brute-force" Electrolysis which still produce notible gains in performance and MPG. With a PWM, you can fine tune the unit and potentially create just as much HHO gas without drawing the amperage....
