How do you define frequency response?

How do you define frequency response?

(Equipment) The ability of a system or elements of the system to react or respond to a change in system frequency. (System) The sum of the change in demand, plus the change in generation, divided by the change in frequency, expressed in megawatts per 0.1 Hertz (MW/0.1 Hz).

What is frequency response physics?

Frequency response is the measure of a system’s response at the output to a signal of varying frequency (but constant amplitude) at its input. The frequency response is typically characterized by the magnitude of the system’s response, measured in dB, and the phase, measured in radians, versus frequency.

What is frequency response of a circuit?

The frequency response of a device or a circuit describes its operation over a specified range of signal frequencies by showing how its gain, or the amount of signal it lets through changes with frequency.

Why is it called a frequency response?

Systems respond differently to inputs of different frequencies. Some systems may amplify frequencies of certain range and attenuate the other frequencies. The way that the system output is related to the input for different frequencies is called frequency response.

What is audio frequency response?

Term: Frequency response (audio) Frequency response is the measure of any system’s output to an input signal of varying frequency (but constant amplitude). Frequency response is typically characterized by the magnitude of the system’s response, measured in dB, and the phase, measured in radians, versus frequency.

What is frequency response of transistor?

General Frequency Considerations. The frequency response of an amplifier refers to the frequency range in which the amplifier will operate with negligible effects from capacitors and device internal capacitance. This range of frequencies can be called the mid-range.

What is frequency response in DSP?

The frequency response of an LTI filter may be defined as the spectrum of the output signal divided by the spectrum of the input signal.

What is a good frequency response in speakers?

What frequency response is good for speakers? The preferred frequency response for speakers is 20 Hz to 20 kHz. The human audio spectrum ranges from 20 Hz to 20 kHz. Speakers should be able to produce sounds in this range.
