在MATLAB中,可以用函数y=filter(p,d,x)实现差分方程的仿真,也可以用函数 y=conv(x,h)计算卷积,用y=impz(p,d,N)求系统的冲激响应。 实现差分方程 先从简单的说起: filter([1,2],1,[1,2,3,4,5]) 实现y[k]=x[k]+2*x[k-1] y[1]=x[1]+2*0=1%(x[1]之前状态都用0) y[2]=x[2...
This function plots a Gaussian impulse response, unit impulse and the % convolution/deconvolution of both using MATLAB's 'filter'. Specifically % it uses 'filter' rather than 'deconv' to do the deconvolution and thereby % returns the original Gaussian vector as well as the unit...
Finite impulse response (FIR) filters are a class of digital filters that only use present and past inputs. FIR filters can be expressed by Eq. 6.5 where all ci coefficients are zero, thus resulting in Eq. 6.7. FIR filters have a finite response to any input. y(n)=FILTERGAIN⋅M...
With the MatLab Control Systems Toolbox, one could linearize the MatLab-Simulink model at several levels of compartmental storage. A transfer function for each linearized model made possible the determination of the impulse response at each linearized condition. The instantaneous unit hydrograph is the...
One of the challenges of the UWOC is that there is no definite mathematical expression for the impulse response function (hc(t)). Hence, hc(t) must be reliably modelled to assess the scope of impacts on the propagated s(t) due to water channel impairments like absorption, single/multiple...
(A) Excitation force coefficient, (B) Added mass coefficient, (C) Radiation damping coefficient, and (D) Impulse response function. Meanwhile, the Simscape SimHydraulic toolbox in MATLAB/Simulink was used to develop the HPTO unit model. The snapshot of the developed model in MATLAB/Simulink ...
In order to get the model of environmental acoustic effect in a room,assuming the model is linear and recognizing the impulse response of the model using correlation analysis method. 为了获得室内环境声效的模型,假定该模型为线性并采用相关分析法辨识室内的脉冲响应。 3. It uses correlation analysis ...
the estimates are computed on a second-by-second basis. The results presented in this paper were computed retrospectively using software developed using Matlab. However, a realtime implementation was developed in the C/C++ programming language to run the algorithms on desktop computers and mobile dev...
