Hybrid filter for lock-in amplifiers
Review of Scientific InstrumentsLock-in amplifiers are instrumental in the precise measurement of extremely small AC signals within high-noise environments. Traditionally, noise reduction in these instruments relies on infinite impulse response (IIR) filters, which can necessitate prolonged settling times to ensure the acquisition of accurate, statistically independent data.

Harmonic Detection for Hybrid Filter
2011Harmonic distortion can be caused by both active and passive nonlinear devices in a power system. These harmonic currents can cause voltage distortion and excessive power losses in the system. To maintain high quality power supply, the system harmonic levels must be measured and kept under control.

Summary form only given. This paper expands polynomial filters to the class of polynomial hybrid (PH) filters. Traditional polynomial filtering theory, based on linear combinations of polynomial terms, is able to approximate important classes of nonlinear systems.

A finite-dimensional filter for hybrid observations
IEEE Transactions on Automatic Control, 1998The paper considers a system whose dynamics are described in terms of the hybrid of a VAR(1)-type process and a discrete state-space Markov chain. It provides a recursive expression for the conditional distributions of these two processes, given a set of observations which are a noisy linear combination of these two processes.

Due to the growing penetration of Internet enabled Electronic mail (Email) services and the greater dependency of Organizations and Individuals on these services, the problem of Spam Electronic Mails, (commonly known as Spam) arises. Existing technologies and algorithms focus on individual parameters of the malicious content. However, efficiency of the

Hybrid multivariate marginal median filters
Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002This paper introduced a new class of hybrid multivariate marginal median filters. The proposed approach combined the noise suppression capabilities of the componentwise median filters and the edge preservation properties of the vector median filters.

Managing hybrid packet filter's specifications
International Journal of Security and Networks, 2012The coexistence of range based and prefix based fields within the filtering policy is one of the most important cause that makes the packet filtering problem difficult to solve and the proposed hybrid solutions hard to implement. Packet filters must support rule sets involving any type of conditions and must scale the number of rules, the number of ...

Processing of the Hybridized Filters
1987After hybridization the filters are washed several times under stringent conditions to remove the excess labeled probe. As explained in the last chapter on hybridization, the stringency of the buffer can easily be increased by lowering the molarity of the monovalent cations and/or increasing the temperature.
