In this paper the convolution z -transform method is applied to obtain an explicit solution of certain nonlinear difference equations. The explicit solution is often desired for system design as well as for obtaining the response for large intervals of time. In these difference equations which ...
The Z-transform and discrete convolutionWhether signals and spectra are initially in discrete or continuous form, to apply digital computational techniques we need discrete versions of both. The analogue-digital conversion process induces errors (and other errors occur in subsequent computation, such as...
We will consider this problem later in this chapter after considering causality, and in the next chapter where we will show that the deconvolution problem can be easily solved using the Z-transform. 6. The computation of the convolution sum is typically difficult. It is made easier when the ...
Standard FFT needs it, but you can reduce arbitrary nn to a convolution (which is doable with powers of 22) with chirp Z-transform. On the other hand, if you only want to compute A(x)B(x)(modxn−1)A(x)B(x)(modxn−1), rather than A(ω)A(ω) for each root of ωn=1...

a在离散时间信号的分析和处理中,常常要对序列进行相加、相乘、延时和卷积等运算,z变换的特性对于简化运算非常有用。 In the discrete time signal analysis and processing, must carry on operations frequently and so on adding together, multiplication, time delay and convolution to the sequence, the z trans...

Such a generalized transform is defined via the generalized H-function of one variable. Conditions for the existence of convolutions of H-transforms are proved. The results are modifications of those by S. B. Yakubovich and Nguyen Thanh Hai [Izv. Vyssh. Uchebn. Zaved., Mat. 1991, No....
Circular convolution using DFT: DFT{x1(n)}={6,0,−2,0}DFT{x2(n)}={10,−2+j2,−2,−2−2j} The product is X(k)=DFT{x1(n)}ċDFT{x2(n)}={60,0,4,0} and inverse transform gives x(n)=IDFT{X(k)}={16,14,16,14} In the above example, linear convolution produ...
Further, the depth of the detected defect was quantified using a recently introduced quantification model using the chirp-z transform-based phase analysis. The estimated depths are rearranged in the respective locations and visualized the depth map....
