Approximation of sine-squared pulse with additional transmission zero using bessel polynomials

Abstract

In this paper, the approximation of sine-squared pulse based on Bessel polynomials with additional transmission zero is presented. The additional transmission zero has a parameter alpha to control the attenuation response. The simulation results show the additional transmission zero can control the peak of attenuation response close to the ideal response. In addition, the orders of Bessel polynomials are decreased that confirm a performance is better than the previous works.
