frequency response

• Medida do espectro de saída de um sistema em resposta a um estímulo, usada em eletrônica, áudio e processamento de sinais para caracterizar como um dispositivo reage a diferentes frequências.

The measure of a system's output spectrum in response to a stimulus, often used in electronics, audio engineering, and signal processing to characterize how a device responds to different frequencies.

1. Signal processing measureC1formal

   The measure of a system's output spectrum in response to an input signal, showing how it amplifies or attenuates different frequencies.

   resposta em frequência

   • The audio engineer analyzed the speaker's frequency response to ensure balanced sound.
   • A flat frequency response is ideal for accurate sound reproduction.
   • The microphone's frequency response curve shows a boost in the high frequencies.

2. Electronic system characteristicC1formal

   The quantitative measure of the magnitude and phase of the output as a function of frequency, used to describe the behavior of amplifiers, filters, and other electronic systems.

   • The amplifier's frequency response was tested from 20 Hz to 20 kHz.
   • A good frequency response ensures minimal distortion in audio equipment.
   • Engineers use frequency response graphs to design better circuits.
