Full Title

Generating pulses having essentially a finite slope or stepped portions > having triangular shape > having sawtooth shape > using as active elements vacuum tubes only > in which a sawtooth voltage is produced across a capacitor > using a tube with negative feedback by capacitor, e.g. Miller integrator > combined with transitron, e.g. phantastron, sanatron
