One thing I'm having trouble with is the term 'voltage intensify'. Stan said that when the outputs from the chokes are combined, the frequency doubles. (Steve verified this on his scope.). Does this mean the voltage is intensified, just by adding more pulses? I always thought intensify means increase, as if two pulses were stacked on top of each other. Doubling the amplitude sharpens the leading edge. Maybe there's another step which Stan left out on purpose, to pull the extra pulses back, to align them with the original pulses, while keeping the frequency the same? Or is the intensifying simply caused by sending the pulses through an inductor, with the accompanying voltage increase? Or would stacking the pulses produce Ed Gray's over/under waveform - a signal which rises and falls, while maintaining a constant potential difference of at least 13.4 V? (Shaking the static.)
