Sine-wave
单一频率的正弦相关法动态测试系统的测试方法简单，不需要对系统进行辨识。只需要观察被测系统输出信号的相差和幅值变化。通过扫频的方法测量在不同的频率点下的幅值和相位变化。在工程应用中，只需要知道被测系统的相位变化在正常的范围内就可以视系统的动态性能正常。该仿真算法只是建立了一个模型。在实际运用时还需要变换测试信号的频率和周期。(A single frequency sinusoidal correlation method of testing dynamic testing system is simple, does not require system identification. Only need to observe the difference between the measured system output signal and amplitude change. Swept through the method of measurement points at different frequencies under the amplitude and phase changes. In engineering applications, only need to know the system under test changes in the normal phase it may be possible within the framework of the dynamic performance of the system to normal. The simulation algorithm is the establishment of a model. In the practical application of test signals also needed to change the frequency and periodicity.)

fir_lin_phase_lowpass_min_order
Designs a linear phase FIR lowpass filter such that it:
- minimizes the filter order
- has a constraint on the maximum passband ripple
- has a constraint on the maximum stopband attenuation
(This is a quasiconvex problem and can be solved using a bisection.
minimize filter order n
s.t. 1/delta <= H(w) <= delta for w in the passband
|H(w)| <= atten_level for w in the stopband
where H is the frequency response function and variable is
the filter impulse response h (and its order/length).
Data is delta (max passband ripple) and atten_level (max stopband
attenuation level).
