sensitivity

In an electronic device, e.g., a communications system receiver, or detection device, e.g., PIN diode, the minimum input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria. (188) Note 1: The signal input may be expressed as power in dBm or as field strength in microvolts per meter, with input network impedance stipulated. Note 2: "Sensitivity" is sometimes improperly used as a synonym for "responsivity."
