Signal detection theory sensitivity
WebEg. The signaling source rarely emits exactly the same sound or photon frequency each trial/ light never emits at exactly 100 photons each flash. 4 possible outcomes in SDT. Correct Decision is made: (1) Hit: say "yes" when a signal is present. (2) Correct Rejection: say "no" when no signal was present. False Decision is made: WebFrequency modulation ( FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and computing . In analog frequency modulation, such as radio broadcasting, of an audio signal representing voice or music, the ...
