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 ...

Here I just think that "XOR convolution in O(k2k)O(k2k)" is the algorithm, and FWHT might be the name of the transform used in the algorithm, but mentioning it instead of XOR convolution for me seems like an obfuscation, like you are trying to hide XOR convolution and/or give it a...
Multiplying the values in each of the spokes and adding them we find the values of a period of v[n], which is given by v1[n]={1n=02n=11n=20n=3Analytically, the Fourier series coefficients of v[n] are V[k]=N(X[k])2=4(X[k])2. Using the Z-transform, X1(z)=1+z−1 ...
MATLAB partial fraction expansion—Consider finding the inverse Z-transform of X(z)=2z−1(1−z−1)(1−2z−1)2|z|>2. (a) MATLAB does the partial fraction expansion: X(z)=A1−z−1+B1−2z−1+C(1−2z−1)2 while we do it in the following form: X(z)=D1−z...

Furthermore, Dirichlet series have Fourier-transform-esque properties, in the sense that Dirichlet series inversion resembles Fourier transforms. It is also interesting to note that L-functions are just Dirichlet series of Dirichlet characters, which are related to group characters used in Fourier trans...
Transforms and Transform Properties DOUGLAS F. ELLIOTT, in Handbook of Digital Signal Processing, 1987 1 Convolution Circular convolution is defined for periodic sequences, whereas convolution is defined for aperiodic sequences. The circular convolution of two N-point periodic sequences x(n) and y(...
Noting the one-to-one correspondence between finite sequences and polynomials with the same coefficients as the sequence (equivalent to the finite z-transform), we also indicate, in Eq. (8.21c), the polynomial representation of finite convolution. The corresponding expression for computing the ...
