Differential gain
Diplex filter
78-715192-01 Rev C
The non-linear change of gain at one level of a signal with
respect to the change of gain at another level for the same
signal. Also, the elimination of redundant information from
an audio, data, or video signal to reduce transmission
requirements.

Data Encryption Standard
The peak difference between the instantaneous frequency
of the modulated wave and the carrier frequency, in an FM
system.
Distributed feed back laser
The difference in amplification of a signal (superimposed
on a carrier) between two different levels of carrier.
A filter which divides the frequency spectrum into a high
frequency segment and a low frequency segment so that
two different signals can be sent down the same
transmission path.
