Transmultiplexer Design Using All-Pass Filters

IEEE Transactions on Communications, 1982
A new scheme for a transmultiplexer is described. Using the polyphase network approach a filter bank composed of only allpass digital filter sections was designed. The use of all-pass filters as basic building blocks is shown to provide a transmultiplexer structure that has low computational requirements, low quantization noise, and high modularity.

On the realization of an all-pass or a notch filter

Proceedings of the IEEE, 1970
It is shown that it is possible to realize either a second-order all-pass or a notch filter by a structure consisting of a grounded operational amplifier and two RC one-ports, Y 1 =G 1 +sC 1 and Y 2 =[R 2 +(1/sC 2 )]-1. It is also shown that these filters may be realized by the same structure with Y 1 and Y 2 interchanged.

Design of stable all-pass filters

ICASSP '79. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
A method for converting the allpass filter design problem to a more tractable spectral factorization problem is presented. Spectral factorization by a new two-dimensional linear prediction technique is discussed, and an efficient lattice structure for implementing the resulting 2-D allpass filter is described.

A simple design for an all-pass filter

International Journal of Electronics, 1975
A new simple design procedure for realizing second-order all-pass transfer functions with arbitrary pole locations is presented. It requires only one difference amplifier of maximum gain 2, two capacitors and four resistors. The coefficient and Q sensitivities, with respect to the amplifier gain, are also studied.

All-Pass Filter Design Using Blaschke Interpolation

IEEE Signal Processing Letters, 2020
Obtaining a rational all-pass filter that matches a target phase response is a common problem in signal processing. Typical approaches have generally focused on optimizing filter coefficients while minimizing the deviation from the target phase response.

An RC all-pass filter†

International Journal of Electronics, 1971
An RC all-pass network with a differential input amplifier and a notch filter is described. It is also shown that an appropriate choice of the notch network can introduce certain advantages in the derived network.

Silicon Based Optical All-Pass Filter

Conference on Lasers and Electro-Optics, 2022
A silicon-based second-order APF is demonstrated. Based on the APF, a microwave photonic phase shifter with simultaneous large phase shift and low amplitude variation is obtained.

The Utility of the All-Pass Filter

IEEE Transactions on Instrumentation and Measurement, 1979
The all-pass filter has seen limited application as a phase-correction circuit for many years. This network can also be applied to many other important areas of electronic design. Applications ranging from inductorless bandpass filters to frequencymodulation circuits are discussed to demonstrate the broad utility of the all-pass network.

An active RC all-pass filter

International Journal of Electronics, 1975
An active RC all-pass filter with a symmetric lattice and a differential input operational amplifier is presented. The realization of the filter requires a less constrained synthesis of the product of a pair of driving-point immittances. The circuit has high performance as regards sensitivity and bandwidth.

Active-RC All-pass Filter

IETE Journal of Research, 1978
The Teramoto method of realizing an RC all-pass is modified to obtain a grounded output with convenient impedance level. Additionally, it is shown that the circuit with a unity-gain amplifier and a little increased complexity of the passive parts, provides the same facilities.
