Classification description:

Indexing scheme relating to amplifiers with only discharge tubes or only semiconductor devices as amplifying elements covered by

Sub-classes:

H03F2203/20 » Indexing scheme relating to power amplifiers, e.g. Class B amplifiers, Class C amplifiers 8
H03F2203/30 » Indexing scheme relating to single-ended push-pull [SEPP]; Phase-splitters therefor 0
H03F2203/45 » Indexing scheme relating to differential amplifiers 10
H03F2203/50 » Indexing scheme relating to amplifiers in which input being applied to, or output being derived from, an impedance common to input and output circuits of the amplifying element, e.g. cathode follower 1
H03F2203/72 » Indexing scheme relating to gated amplifiers, i.e. amplifiers which are rendered operative or inoperative by means of a control signal 2
