Design of Digital Notch Filters for Dynamic Strain Gauges
Wenbin Wei · Journal of Guangxi University of Technology · 2011
A power frequency notch filter is designed for dynamic strain gauges,which is based on the ripple properties of the Chebyshev function to regulate the stopband's attenuation characteristics of filters so as to improve the steep transition band and its breadth.Simulations and actual signal processing prove that this design can satisfy the performance requirements of a power frequency notch filter for dynamic strain gauges.
