What is complex frequency response?
The complex frequency response function of a system represents the complex relation between two signals (result curves from a time range). It is defined as the Fourier transform of one signal divided by the Fourier transform of the other signal: X ... signal2(input)
What is frequency response time?
A frequency response describes the steady-state response of a system to sinusoidal inputs of varying frequencies and lets control engineers analyze and design control systems in the frequency domain.
How do you find the frequency response of a function?
First we substitute s = jω into H(s) to obtain an expression of the frequency response. Note that the numerator and the denomator are both complex. To obtain the amplitude response, we take the absolute value of H(jω). To do this, we evaluate the magnitude of the numerator and the denominator separately.
What is the purpose of a frequency response function?
A Frequency Response Function (FRF) is a function used to quantify the response of a system to an excitation, normalized by the magnitude of this excitation, in the frequency domain.
