Class 327: Miscellaneous Active Electrical Nonlinear Devices, Circuits, And Systems
This is the residual class for electrical devices, circuits or systems having an output not directly proportional to its input and comprising at least one component which can provide gain or can route electrical current and which device, circuit or system does not form a complete system such as is classified specifically elsewhere or a subcombination of utility only in such elsewhere classified system.Subclass 14: Slope
Subclass 558: Lowpass
Subclass 58: Maximum or minimum amplitude
Subclass 98: By separating composite signal
Class 330: Amplifiers
This is the generic class for amplifiers, included: Amplifiers having all types of active elements (or amplifying devices), amplifier systems having plural amplifier channels, cascade amplifiers, push-pull amplifiers and other amplifiers having plural amplifier devices. Also included are amplifiers with plural signal sources or plural loads. Amplifiers including the means coupling the signal source to the amplifier or coupling the amplifier to the load or between cascaded stages are also included. Amplifiers combined with tone control means. Amplifiers combined with amplitude (volume) control means whether by manual control, by control of an electrode D.C. bias. Amplifiers combined with power supply. Amplifiers combined with structural features of the amplifier or the amplifier circuit elements. Amplifiers having signal feedback means.Subclass 292: Having compensation for interelectrode impedance
Subclass 310: Including plural stages cascaded
Class 365: Static Information Storage And Retrieval
Apparatus or corresponding processes for the static storage and retrieval of information. For classification herein, the storage system must be (1) static, (2) a singular storage element or plural elements of the same type, (3) addressable.Subclass 64: Optical
Subclass 106: RADIANT ENERGY
Subclass 230.03: Plural blocks or banks
