Decibels in electronics
WebView history. The sensitivity of an electronic device, such as a communications system receiver, or detection device, such as a PIN diode, is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria. In signal processing, sensitivity also relates to ... WebLogarithmic units and decibels Power gain. Power gain, in decibels (dB), is defined as follows: = , where is the power applied to the input, is the power from the output.. A similar calculation can be done using a natural logarithm instead of a decimal logarithm, resulting in nepers instead of decibels: = . Voltage gain. The power gain can be …
