This work is dedicated to the approximation of the integrator in the digital domain. The working principle of the proposed digital integrator (DI) optimizes the generalized transfer function based on fractional bilinear transform (FBLT) and subsequently, the multirate technique is employed to reduce the magnitude error. The obtained design correlates the corresponding ideal response and provides the absolute relative magnitude error (ARME) and the mean relative magnitude error (MRME, dB) as 0.1752 and -64.954 dB respectively. The comparison is done with the published DI's to show its viability in terms of low magnitude errors.
