IMPEDANCE COUPLING
uses a coil as a load for the first stage but otherwise functions just as
RC coupling.
Impedance coupling
is used at high frequencies.
TRANSFORMER COUPLING
uses a transformer to couple the signal from one stage to the next.
Transformer coupling
is very efficient and the transformer can aid in
impedance matching
.
