We have already discussed three circuits—the difference diode relaxation oscillator, the thyratron relaxation oscillator and the blocking oscillator— Forward stroke. Flyback (rapid discharge) Figure which produce waveforms of approximately triangular—in fact exponential — form. The degree to which the exponential produced resembles the ideal form depends on how much of it is used; if the capacitance is allowed to charge only to 1 per cent or so of the total charging voltage available HT-i- HT*.
