The Ensemble Kalman filter: a signal processing perspective [PDF]
EURASIP Journal on Advances in Signal Processing, 2017 The ensemble Kalman filter (EnKF) is a Monte Carlo-based implementation of the Kalman filter (KF) for extremely high-dimensional, possibly nonlinear, and non-Gaussian state estimation problems.

LUT Filters for Quantized Processing of Signals [PDF]
IEEE Transactions on Signal Processing, 2004 We introduce a method to perform filtering on approximations (quantized versions) of the input signal, which lends itself to a practical implementation solely based on look-up tables (LUTs). The LUT filter approximates the performance of some traditional nonlinear filters at a fraction of the cost. The filter is divided into an approximation stage that

A Time-Mode PWM 1st Order Low-Pass Filter
Journal of Low Power Electronics and Applications, 2023 In this work, a first-order low-pass filter is proposed as suitable for time-mode PWM signal processing. In time-mode PWM signal processing, the pulse width of a rectangular pulse is the processing variable.

Digital filtering and signal processing [PDF]
Behavior Research Methods & Instrumentation, 1973 The design, realization, and some of the many uses of digital filters are reviewed. Computer programs coded in FORTRAN are presented for the design of lumped parameter digital and analog filter systems which are simulated on a digital computer. Explanations of the programs are accompanied by examples of their use.
