always exists whether a signal is present or not

5
New cards

shot noise

present in all semiconductors. Reason: a change passes a p-n junction.

dB unit

a transmission-measuring unit used to express relative gains and losses of electronic devices and circuits, and for describing relationships between signals and noise.
