Title: Frequency truncated discrete-time system norm,
Abstract: Multirate digital signal processing and model reduction applications require
computation of the frequency truncated norm of a discrete-time system. This
paper explains how to compute the frequency truncated norm of a discrete-time
system. To this end, a much-generalized problem of integrating a transfer
function of a discrete-time system given in the descriptor form over an
interval of limited frequencies is also discussed along with its computation.
