... The analysis is done assuming that the signal frequency is sufficiently high. Subsequently it can be assumed that all the coupling capacitors (C1 and C2) and the bypass capacitor (CE) act as perfect short circuits. Such a frequency is said to be in the mid band of the amplifier. The hybrid-π model a ...

Metadyne
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
