(under the class definition) Subject matter relating to systems for producing pulses or shaping waves.
(1) Note. This subclass relates, for example, to systems having an easily saturated transformer which produces a pulse output when over excited at its input or to other systems having nonlinear elements.
(2) Note. This subclass relates, for example, to systems producing pulses of particular wave shape.
SEE OR SEARCH THIS CLASS, SUBCLASS:
96+, for means for producing square waves by intermittent interruption of a circuit in which the ratio of the conduction to nonconduction state is variable, as, for example, in Tirril regulators.
132, for means for producing square waves by intermittent interruption of a circuit, where the ratio of conduction to nonconduction is not varied.
SEE OR SEARCH CLASS 84, Music,
600+, for electrical musical instruments having means to produce wave forms of desired shape.
331, Oscillators, appropriate subclasses, for electrical oscillators in general, particularly
