The modifications of low pass filter responses by the generalized bessel transformation with equal-ripple attenuation in the stopband

Abstract

In this paper modification of low-pass filter responses by the application of Generalized Bessel transformations with equal-ripple attenuation in the stopband. A function has been developed which enable filter designs to place the flattest portion of the magnitude curve at a frequency in the passband other than ω = 0. In comparison with Maximally Fate Delay (MFD), these filters have steeper slops at cutoff and provide more high-frequency attenuation.
