Abstract

A novel efficient approximation for linear phase FIR based Multiband Pass Integrator (MPI) of ideal magnitude response, 1/(j 𝝎) as well as for |1/ 𝝎|, have been proposed without using fractional delays. The suggested approximations yield highly accurate response over a band of frequencies centered around different πŽπ’Ž simultaneously. The points of maximal flatness πŽπ’Ž can be chosen arbitrarily in the frequency range 0 <πŽπ’Ž<𝝅. As compared to previous single band integrators, relative error in Multiband Pass Integrator is reduced to a large extent. For 𝑯𝒏,π’Ž(𝝎) relative error observed is in the range of [2, 36]% and for 𝑭𝒏,π’Ž(𝝎) is [4.363, 30.636]%. Respective graphs for errors, are thus obtained for both 1/(jΟ‰) and for |1/Ο‰|.
