As now our more emphasis is on saving power and bandwidth
in communication,so we used digital
communication.Communication electronics includes the use of
elctronics devices and system for transmission,analysing
and amplification of signal.

Power elctronics as the name suggest deal with large power
that is not in case of ordinary device like diode and
transistor.For high power application we use
Thyristor,Triac,Diac.

Unlike three state in transistor i.e.
cutoff,active,saturation. In digital electronics there are
only two states on(cutoff) and off(saturation).This is
called digital as we got output in two forms only either
high or low.Various elements of logic family are
CMOS,TTL,RTL,DTL,HTL.
