Class:: ELECTRONIC CIRCUITRY
Subclass:: PULSE TECHNIQUE

Description

H03K covers electronic circuits and devices designed to generate, process, shape, or detect electrical pulses and pulse trains. This subclass encompasses oscillators, pulse generators, timing circuits, monostable and astable multivibrators, counters, and dividers that operate on discrete pulse signals rather than continuous waveforms. Applications include digital logic circuits, switching circuits, timing control systems, and pulse modulation techniques used in telecommunications, radar, and digital electronics. The classification excludes steady-state signal processing and continuous-wave techniques, which fall under other H03 subclasses.
