Note(s)
This subclass covers:linear amplification, there being linear relationship between the amplitudes of input and output, and the output having substantially the same waveform as the input;dielectric amplifiers, magnetic amplifiers, and parametric amplifiers when used as oscillators or frequency-changers;constructions of active elements of dielectric amplifiers and parametric amplifiers if no provision exists elsewhere.
