Wideband Agile Transversal Filter

MTT-S International Microwave Symposium Digest, 2005
The development of a Wideband Agile Transversal Filter is made possible by the use of dual gate GaAs FET transistor arrays. The transversal filter design has a bandwidth of greater than 2.0 GHz and the filter transfer function can be changed in less than 10 nanoseconds.

Interleave filter based on coherent optical transversal filter

Journal of Lightwave Technology, 2006
The principle of the transversal interleave filter previously proposed as a novel class of interleave filter is described. The principle of a conventional 1 /spl times/ 1 coherent optical transversal filter is reviewed. Then, the fundamental operating principle and the three design conditions required for the novel interleave filter are explained.

Tunable microwave photonic transversal filter

International Journal of Microwave and Wireless Technologies, 2015
We present a tapped tunable delay line filter for radiofrequency (RF) photonic filtering applications, capable of rapid tunability over a wide RF bandwidth limited only by the optical components’ losses, while maintaining independence from polarization state.

Transversal dielectric resonator filter design

Proceedings of 8th Mediterranean Electrotechnical Conference on Industrial Applications in Power Systems, Computer Science and Telecommunications (MELECON 96), 2002
This article describes a transversal dielectric resonator (D.R.) filter and the procedure which can be applied to design this device starting from the synthesis of conventional filter. An example of a three poles transversal structure is presented. The result is compare to a rigorous analyse using the three dimensional finite element method.

An adaptive transversal filter VLSI

ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
This paper describes a hardware architecture of an adaptive transversal filter with long delay taps and its LSI implementation. We developed an adaptive transversal filter VLSI with 512 taps which is suitable for an echo canceller system. We developed a new compuatational method suitable for VLSI implementation, and clarified the required computation ...

An adaptive transversal filter

ICASSP '83. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
A real time electronically programmable transversal filter with parallel architecture is described. The device is capable of operating at sampling rates in excess of 500KHz while maintaining high dynamic range. The device is built around an analog delay line designed using operational amplifiers and switching circuitry.

Transversal filters—a simple implementation

International Journal of Electronics, 1981
A method for implementing transversal fitters based on the conversion of the voltage input signal to the pulse width modulated form is described. The circuit proposed uses monostable multivibrators, analogue switches and operational amplifiers. An alternative scheme is also suggested.
