, 2016 Power converters require passive low-pass filters which are capable of reducing voltage ripples effectively. In contrast to signal filters, the components of power filters must carry large currents or withstand large voltages, respectively. In this paper,

Passive loop filter assistance for CTSDMs [PDF]
IEEE Transactions on Circuits and Systems II: Express Briefs, 2017 This paper presents a power reduction technique for continuous time sigma delta modulators (CTSDM). The approach consists of two elements. First, a passive low pass filter is added in front of the modulator's loop filter to reduce the high frequency ...

On the Importance of Passive Acoustic Monitoring Filters [PDF]
Journal of Marine Science and Engineering, 2021 Passive acoustic monitoring (PAM) is a noninvasive technique to supervise wildlife. Acoustic surveillance is preferable in some situations such as in the case of marine mammals, when the animals spend most of their time underwater, making it hard to obtain their images.

Passivity Filter for Variable Impedance Control [PDF]
2020 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2020 While impedance control is one of the most commonly used strategies for robot interaction control, variable impedance control is a more recent preoccupation. If designing impedance control with varying parameters allows increasing the system flexibility and dexterity, it is still a challenging issue, as it may result in a loss of passivity of the ...

Optimal sizing of C-type passive filters under non-sinusoidal conditions [PDF]
, 2014 In the literature, much attention has been focused on power system harmonics. One of its important effects is degradation of the load power factor. In this article, a C-type filter is used for reducing harmonic distortion, improving system performance ...

A hybrid active filter for damping of harmonic resonance in industrial power systems [PDF]
, 1998 This paper proposes a hybrid active filter for damping of harmonic resonance in industrial power systems. The hybrid filter consists of a small-rated active filter and a 5th tuned passive filter.

Tunable Optical Filters Using Compound Ring Resonators for DWDM [PDF]
, 2003 The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a directional coupler. The loop mirror is implemented using a Sagnac configuration to have the same optical path between the ...

Very low sensitivity FIR filter implementation using 'structural passivity' concept [PDF]
, 1985 The concept of "structurally bounded" or "structurally passive" FIR filter implementation is introduced, as a means of achieving very low passband sensitivities.

Understanding the Global in Global Finance and Regulation [PDF]
, 2014 A simple and statistically robust method for passive clock synchronization in sensor networks is presented. The method is not limited to passive (one-way communication) synchronization, but this scenario justifies the method.

A practical approach to harmonic compensation in power systems-series connection of passive and active filters [PDF]
, 1991 The authors present a combined system with a passive filter and a small-rated active filter, both connected in series with each other. The passive filter removes load produced harmonics just as a conventional filter does.
