Sensitivity
The greater the sensitivity, the greater the system′s signal-to-noise ratio.
- For an ammeter, the amount of current that will cause full-scale deflection of the meter.
- For a voltmeter, the ratio of the voltmeter resistance divided by the full-scale reading of the meter; expressed in ohms per volt.
- The ability of a receiver to reproduce very weak signals. The greater the receiver sensitivity, the weaker the signal that can be reproduced.
- Efficiency of a microphone. Describes microphone power delivered to a matched-impedance load as compared to the sound level being converted. Usually expressed in terms of the electrical power level.
