H03K3/12 - CPC Classification

Circuits for generating electric pulses; Monostable, bistable or multistable circuits; Generators characterised by the type of circuit or by the means used for producing pulses by the use, as active elements, of vacuum tubes only, with positive feedback using means other than a transformer for feedback using at least two tubes so coupled that the input of one is derived from the output of another, e.g. multivibrator bistable

• H03K3/13 » Bistables with hysteresis, e.g. Schmitt trigger 8
