up from electrical appliances existing ____________________
In the vicinity
From the atmosphere
From electrical transformers
Also from outer space
All of these
Internal noise is generated in the
Channels
Receivers
Transmitter

Low frequency
Middle frequency
No frequency
External noise has _______ effect on
higher frequencies
More
Less
No
None of these
Internal noise is fairly low in case
of
