Group-velocity dispersion in an all-pass Bragg filter

Optics Letters, 1994
On the basis of previously performed theoretical analysis it is shown that a slanted volume grating acts as an all-pass filter with nonlinear dispersion when the diffracted wave is evanescent. An analytical expression for the grating transfer function applicable over a wide angular range of mutual orientation of the initial wave and grating vectors is ...

A new method for digital all-pass filter design

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1987
A new method for the design of digital all-pass filters using Chebyshev criterion is introduced. It is based on a phase approximation algorithm for polynomial transfer functions. The algorithm exploits a scheme of iteratively linearizing the nonlinear constraints in a nonlinear programming and converges theoretically.

A new designing method of filter banks using all-pass polyphase filters

[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992
A new designing method for uniform filter banks using all-pass filters is presented. This method is based on the two-stage filter bank structure using all-pass filters. By using this method, the authors realized a continuous soft-band property for polyphase filters and analysis filter banks. Moreover, the realization of synthesis filter banks is given.

On the design of digital filters as a sum of two all-pass filters

IEEE Transactions on Circuits and Systems, 1985
The necessary and sufficient conditions are given for a digital filter transfer function to be implementable as a sum of two all-pass filters. The conditions are derived directly in the z -plane. The class of filters satisfying these conditions is shown to be wider than the class of filters obtained via the bilinear transformation from the ...
