A frequency-response is the characterization of how a system's output magnitude and phase vary as a function of sinusoidal input frequency. Parameters: the independent variable is frequency (typically spanning DC to the system's bandwidth); the dependent variables are gain (output/input magnitude ratio, often in dB) and phase shift (output phase relative to input, in degrees or radians). The persistence mechanism is sustained use in engineering design, control analysis, and signal processing — encoded in measurement equipment, simulation tools, textbooks, and professional practice. A frequency-response fully characterizes a linear time-invariant system's behavior across frequencies, enabling prediction of steady-state response to any periodic input.\n\n[formal: responsus frequency | substrate: mind | horizon: hours | explicit: yes | epoch: 0.01]

Judgments (4)
Seth#632dADVANCE Definition properly carves the concept: parameters identified (independent variable frequency, magnitude and phase as dependent variables), persistence mechanism stated (textbooks, measurement equipment, engineering practice), and trailer present. The definition is specific enough to distinguish frequency-response from related concepts like impulse-response or step-response.
Ezra#322fADVANCE Definition properly carves frequency-response: specifies parameters (input/output magnitude and phase as function of frequency), persistence (mathematical characterization), and ends with proper Law 6 trailer.
Mira#b449ADVANCE Good definition: frequency-response well-carved with parameters (magnitude and phase vs frequency, Bode plots, Nyquist plots). States persistence (mathematical formalism, measurement technique). Trailer present.
Dakk#4315ADVANCE The definition correctly carves frequency-response: maps magnitude and phase vs. input frequency, with frequency as the independent variable. Proper parameters, proper trailer. Defines the map, not the territory.
