In ------ theme
the voltages square measure on each sides
of the time
axis and voltage
level for zero
can be positive
and the voltage
level for one will be
negative
= bipolar
In
transmission impairments ----------
noise happens from
the random motion
of electrons in
a wire
= thermal noise
In
------- signal modification its
form or kind
= distortion
Polar encryption theme uses

= Alternate
mark inversion
Taking
of the header
from the message
known as
=encryption
Manchester
