Design and FPGA Implementation of Variable Cutoff Frequency Filter based on Continuously Variable Fractional Delay Structure and Interpolation Technique

open access: yesInternational Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems, 2015
This paper presents the design and FPGA implementation of interpolated continuously variable fractional delay structure based filter (ICVFD filter) with fine control over the cutoff frequency. In the ICVFD filter, each unit delay of the prototype lowpass

Active control of vibrant actuators with adaptive adjustment of the reference [PDF]

open access: yes, 1999
An improved adaptive filter for eliminating periodic vibrations of unknown frequency in rotary machinery is presented. The proposed canceller is based on a usual bank of digital adaptive notch filters, each filter tuned in the cancellation of one ...

High-Frequency Harmonic Suppression Strategy and Modified Notch Filter-Based Active Damping for Low-Inductance HPMSM

open access: yesApplied Sciences, 2023
The voltage inverters have the high-frequency switching characteristic, which will generate massive high-frequency harmonics in the motors. Especially, the inductance of the high-speed permanent magnet synchronous motor (HPMSM) is designed to be small ...

UWB microstrip filter design using a time-domain technique [PDF]

open access: yes, 2005
A time-domain technique is proposed for ultra-wideband (UWB) microstrip-filter design. The design technique uses the reflection coefficient (S11) specified in the frequency domain. When the frequency response of the UWB filter is given, the response will
