A feedforward active noise control system includes the secondary path filter for compensation of acoustic coupling between loudspeaker and reference microphone. In ordinary systems, the filter is designed to be a pre-set type, without any system identification for it, because the adaptation of its filter taps without any additional noise is difficult. This paper introduces a new identification ...

Original scientific paper The Kalman filter is a very general method of filtering which can solve problems such as optimal estimation, prediction, noise filtering, and optimal control. A problem with detection of correct path of moving objects is the received noisy data. Therefore, it is possible that the information is incorrectly detected. There are Different methods to extract the correct da...

In this paper, a simple but effective method for compensation of the quadrature error in MEMS vibratory gyroscope is provided. The proposed method does not require any change in the sensor structure, or additional circuit in the feedback path. The mathematical relations of the proposed feedback readout system were analyzed and the proposed solution assures good rejection capabilities. Based on ...

Finite Impulse Response (FIR) Filter can be designed by the provision of specifications which are for a particular application requirement. An efficient FIR filter is designed using register reduction retiming technique. Also, an optimization environment is designed such that filter components of post retimed circuit such as adder and multiplier are upgraded depending on the Very Large Scale In...

The structure of many standalone network intrusion detection systems (NIDSs) centers around a chain of analysis that begins with packets captured by a packet filter, where the filter describes the protocols (TCP/UDP port numbers) and sometimes hosts or subnets to include or exclude from the analysis. In this work we argue for augmenting such analysis with an additional, separately filtered stre...

A widely tunable 4th order BPF based on the subtraction of two 2nd order 4-path passive-mixer filters with slightly different center frequencies is proposed. The center frequency of each 4-path filter is slightly shifted relative to its clock frequency (one upward and the other one downward) by a gm-C technique. Capacitive splitting of the input signal is used to reduce the mutual loading of th...
