This leads to powerful methods of analyzing systems and considering how the amplitude and the phase of the output signal varies as the frequency of the input sinusoidal signal is changed. This variation is terme
Sinestream input signals are the most reliable input signals for estimating an accurate frequency response of a Simulink model using the frestimate function. A sinestream signal is composed of individual sinusoidal signals that are appended to each other. The frestimate function simulates the model fo...
The frequency response of a physical plant is estimated during real-time operation with the Frequency Response Estimator block. This blocks injects sinusoidal test signals into the plant at the nominal operating point and the frequency response is continually refined as the output signal data is coll...
The frequency response of a linear system is defined as the sinusoidal deviations in a system's output resulting from a sinusoidal deviation in the system's input. From:Dynamics and Control of Nuclear Reactors,2019 Also in subject areas: ...
This MATLAB function estimates the frequency response of a Simulink model using the specified input signal, the operating point defined by the model initial conditions, and the analysis points specified in io.
The frequency response The frequency response of a circuit is the variation in its behavior with change in signal frequency. Magnitude →amplitude response 幅频响应; 模→幅频响应; 幅频响应 Phase →phase response 幅角→相频响应。 幅角 相频响应。 相频响应 I/Io 1 θi 90° 0.707 Q1 ω Q1...
Frequency Response of Discrete-Time Systems A spectrum of input sinusoids is applied to a linear time invariant discrete-time system to obtain the frequency response of the system. The frequency response of the discrete-time system gives the magnitude and phase response of the system to the input...
Then, using frequency estimators, we estimate the frequencies of the sinusoids from the filtered data. The results presented in this paper demonstrate that the proposed algorithm provides a better resolution ability and estimate accuracy than that of the conventional AR spectral estimator, especially ...
41 suggested that the low-frequency response of the PC channel is restricted to pulsatile stimuli, whereas we (like many previous studies) have used sinusoidal stimuli. Moreover, even if PC afferents did partially contribute to our measures of acuity for low-frequency vibrations, this does not ...
However, when the optical pulses are detected directly, it is the much slower response time of the photodetector, Tresp ≫ Tp, that limits the distance/timing resolution. By employing a second comb, linear-optical sampling (LOS) is used to circumvent the photodetector response limit. LOS...
