BANDPASS VIBRATION ABSORBER

Journal of Sound and Vibration, 1998
Abstract A new concept for active vibration absorption is presented. A properly designed compensator in the local feedback converts the well-known passive absorber into a bandpass absorber. Such an absorber amplifies frequencies in a given frequency range, thus almost producing resonance for all these frequencies. If such an absorber is attached to a

OFDM IN BANDPASS NONLINEARITY

International Conference on Consumer Electronics, 1996
The behavior of orthogonal frequency division multiplexing (OFDM) signals in bandpass nonlinearity is presented. In particular, in-band bit-error-rate (BER) degradation and induced adjacent channel interference, as a result of amplitude limiting or clipping, are analyzed.

The Optimization of the Bandpass Lengths in the Multi-Bandpass Problem

2013
The Bandpass problem has applications to provide a cost reduction in design and operating telecommunication network. Given a binary matrix Am × n and a positive integer B called the Bandpass length, a set of B consecutive non-zero elements in any column is called a Bandpass. No two bandpasses in the same column can have common rows.

Inductorless bandpass filters

IEEE Journal of Solid-State Circuits, 1970
The technique of designing inductorless filters by replacing the inductors in conventional LC filters with gyrators and capacitors is considered for the special case of the high-quality channel bandpass filters used in multiplex telephony. One particular gyrator circuit, which has been found to be very satisfactory, using two operational amplifiers and

Dielectric square bandpass design

Applied Optics, 1981
Two concepts new in square bandpass design make the design process easier and more systematic. One is the use of adjacent high-order rejection bands. The second is the use of effective index ratio. This paper extends the work of L. I. Epstein [J. Opt. Soc. Am. 42 806 (1952): "The Design of Optical Filters"] and A. Thelen [J. Opt. Soc. Am. 50 1533 (1966)

Bandpass sampling and bandpass analogues of prolate spheroidal functions

Signal Processing, 2006
We use the bandpass form of sampling theorem to construct a set of finite support functions that have highest energy concentration in bands of frequencies centered on a given carrier-frequency. These functions form an orthogonal set similar to the angular prolate spheroidal functions of order zero and hence we refer to them as "bandpass analogues of ...
