The delayed impact of group therapists' interventions
Journal of Clinical Psychology, 1977The direct and delayed impact of therapist interventions on 21 clients in three outpatient therapy groups was examined. Sessions one and five of each group were taped with every therapist intervention analyzed according to the Group Therapist Interventions Scale and every client utterance rated on the Experiencing Scale and categorized by the Group ...

On two-dimensional group delay equalization
IEEE Transactions on Circuits and Systems for Video Technology, 1991The authors focus on some peculiarities of 2-D group delay equalization by means of cascades of 2*2 sections, a 2-D equalization technique that has lately received considerable attention. It appears that the group delay performance obtained by just one or two 2*2 section equalizers cannot be significantly improved by using equalizers with a greater ...

Group delay analysis of switched circuits
1993 IEEE International Symposium on Circuits and Systems, 2002An analysis of group delay and its sensitivity to element values of periodically switched linear circuits is presented. The theory is exact and handles multiphase switches and all types of linear elements, including resistors and inductors. Applications include analysis and design of phase equalization networks for nonideal switched capacitor filters ...

Noise and Group Delay in Active Filters
IEEE Transactions on Circuits and Systems I: Regular Papers, 2007The output noise spectrum and the group delay of active filters are related. For any state-space realization of any transfer function without finite transmission zeros, there is a combination of noise transfer functions that is equal to the group delay.

A Broadband Dual‐Band Negative Group Delay Circuit With Flat Group Delay
International Journal of Circuit Theory and ApplicationsABSTRACTA broadband dual‐band negative group delay circuit (NGDC) with flat group delay is proposed. Without the cascade structure, the proposed NGDC consists of an open‐circuited coupled lines connected with a resistor through transmission lines and a matching network.

Lowpass delay filters with flat magnitude and group delay constraints
IEEE Transactions on Signal Processing, 2003This paper describes the design of finite impulse response (FIR) delay filters that minimize a squared error and have prescribed number of zeros at /spl omega/=/spl pi/ and prescribed magnitude and group delay flatness at /spl omega/=0. An important special case is the design of least squared error lowpass filters with prescribed flatness constraints ...

Simple series for phase angle, delay, and group delay
IEEE Transactions on Circuits and Systems, 1979Simple power series in \omega for the phase angle, delay, and group delay due to a conjugate pair of complex poles or zeros are presented, and an example of their application to the design of phase equalizers is given.
