Thesaurus| Noun | 1. | frequency response - (electronics) a curve representing the output-to-input ratio of a transducer as a function of frequencysensitivity, sensitiveness - the ability to respond to physical stimuli or to register small physical amounts or differences; "a galvanometer of extreme sensitivity"; "the sensitiveness of Mimosa leaves does not depend on a change of growth"electronics - the branch of physics that deals with the emission and effects of electrons and with the use of electronic devicesoutput-to-input ratio - the output power of a transducer divided by the input power |
frequency response
frequency response[′frē·kwən·sē ri‚späns] (engineering) A measure of the effectiveness with which a circuit, device, or system transmits the different frequencies applied to it; it is a phasor whose magnitude is the ratio of the magnitude of the output signal to that of a sine-wave input, and whose phase is that of the output with respect to the input. Also known as amplitude-frequency response; sine-wave response. frequency responseIn an audio system, the accuracy of sound reproduction. A totally flat response means that there is no increase or decrease in volume level across the frequency range. Measured in decibels (dB), this would be plus or minus 0 dB from 20Hz to 20,000Hz. A high-end audio system can deviate by +/- 0.5 dB, but a CD-ROM drive should not be off by more than +/- 3 dB.MedicalSeefrequencyAcronymsSeeFRfrequency response
