H03K4/12 - CPC Classification

Classification description:

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

Sub-classes:

H03K4/14 » using two tubes so coupled that the input of each one is derived from the output of the other, e.g. multivibrator 0
H03K4/16 » using a single tube with positive feedback through transformer, e.g. blocking oscillator 0
H03K4/18 » using a single tube exhibiting negative resistance between two of its electrodes, e.g. transitron, dynatron 0
H03K4/20 » using a tube with negative feedback by capacitor, e.g. Miller integrator 0
H03K4/24 » Boot-strap generators 0
