Definition of frequency response in US English:

frequency response


  • The dependence on signal frequency of the output–input ratio of an amplifier or other device.

    • ‘Compressionists fiddle with the picture's frequency response and the data-transfer rate of the digital bit stream because generally, the higher the transfer rate, the better the picture.’
    • ‘Because of variations in circuit frequency response, the recovered levels of the 404Hz and 2804Hz tones will be different than that of the 1004Hz tone.’
    • ‘The frequency response was 0.05 to 100 Hz.’
    • ‘The stated frequency response is 30 Hz to 90 Hz.’
    • ‘The system response signal divided by the input signal represents the frequency response of the system.’
