Inductorless low-pass filters

IEEE Journal of Solid-State Circuits, 1971
High-quality inductorless lowpass filters of even degree with resistive source and load impedances can be constructed using Riordan's gyrator circuit with a modification of Bruton's method, in which the admittance of each element is multiplied by P. Some experimental results were extremely good.

Low-pass active filters

Radio and Electronic Engineer, 1967
Microminiature active filters have been constructed using a combination of thin film and integrated circuits. The advantages of such an approach are discussed. The filter required could be met by a fifth-order Chebyshev function and the method of realization was to split the transfer function into quadratic and linear factors with each factor then ...

Multimode Waveguide: A Low Pass Filter

Applied Optics, 1973
It is shown in this paper that a multimode waveguide-represented by a ray model-acts like a low-pass filter with respect to the modulation. The response function is calculated and discussed in the case of an ideal, straightlined, loss-free system.

Grating low-pass filters

Infrared Physics, 1992
Abstract Gratings are excellent low-pass filters, provided they have the appropriate mounting. We have measured the spectral reflectivity of filters composed of four gratings, from the 0.2 mm to 2 mm wavelength region. In order to contain the size of the gratings, they were placed near a lens focus, where the beam section is smaller.

Low-Pass Filter Topologies

2014
Low-pass filters are systems that allow the passing without attenuation of signals with frequency below the cutoff frequency, while attenuating those with frequency above it. The amount of attenuation the signals with higher frequency suffer is dependent on their frequency and the order of the filter.

Miniature low-pass EMI filters

Proceedings of the IEEE, 1979
This paper describes miniature ceramic feedthru type electromagnetic interference (EMI) filters. Electrically, the devices function as low-pass filters with a 3-dB cutoff frequency in the low-megahertz range. The filters are mechanically rugged and in many applications can be placed in the I/O connector or substituted for the existing feedthrus.

Digital low-pass filtering.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1976
Random noise beyond the maximum signal frequency of the imaging system can be removed by low-pass filtering without compromising signal transmission.

Pulse modification by low pass filters

Applied Optics, 1986
Calcul des effets induits par un filtre de frequences passe bas sur l'amplitude et la forme d'une impulsion courte. On etudie la possibilite d'appliquer ces resultats pour etudier la localisation de la bande d'absorption dans le domaine temps a la place du domaine ...

Grating Optical Low-Pass Filter

Japanese Journal of Applied Physics, 1996
The spurious signals appearing in the picture image from a charge-coupled semiconductor device (CCD) camera were removed by means of a novel grating optical low-pass filter (GOLF). By placing the GOLF near the imaging plane of the CCD and adjusting the effective grating period projected onto the imaging plane with respect to the array ...

Dissipative low-pass filter

1988
The filter comprises a series branch formed by an inductance coil (L) in parallel with a resistor (R1) and a parallel branch formed by a capacitor (C) in series with a resistor (Rc).
