Frequency Response
Electrical Engineering · Mechatronics & Robotics · Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The steady-state response of a circuit or system to sinusoidal inputs at various frequencies, typically represented by a magnitude and phase plot.
Example in context
“The frequency response of the filter shows a flat passband from 100 Hz to 10 kHz and a roll-off above 15 kHz.”
“Filtrenin frekans cevabı, 100 Hz ile 10 kHz arasında düz bir geçiş bandı ve 15 kHz'in üzerinde bir düşüş gösterir.”
Where engineers use it
This term appears in filter design, amplifier specification, and control systems. Engineers use it to assess system stability, bandwidth, and distortion over different operating frequencies.
Synonyms: Bode plot, gain-phase plot
Antonyms: transient response
In Mechatronics & Robotics
Frequency response describes how a system's output magnitude and phase change relative to its input over a range of sinusoidal frequencies. It is a key tool for analyzing dynamic behavior in the frequency domain.
“The engineer measured the frequency response of the servo motor to determine its bandwidth and resonance frequencies.”
In Electronics Engineering
A description of how a circuit's gain and phase vary with the frequency of the input signal.
“The engineer measured the amplifier's frequency response to confirm it remained flat across the audio band.”
Practice: can you use “Frequency Response” at work?
You are reviewing a motor driver datasheet; the Bode plot shows a drop in gain at high frequencies. Explain what the frequency response tells about the driver's ability to switch fast.
