Noun
A measure of responsiveness
(physics) A measure of the gain of a system
Source: en.wiktionary.orgFor a system that responds linearly to its input, there is a unique responsivity. Source: Internet
From this metric noise-equivalent power can be computed by taking the noise level over the responsivity. Source: Internet
Furthermore, the term gain is also applied in systems such as sensors where the input and output have different units; in such cases the gain units must be specified, as in "5 microvolts per photon" for the responsivity of a photosensor. Source: Internet
In this case, responsivity summarizes the change in the neural response per unit signal strength. Source: Internet
The broad-band responsivity, is then just the signal weighted by this wattage. Source: Internet
The responsivity in these applications can have a variety of units. Source: Internet
