IIR filter transient suppression by signal shifting

Transient responses are a common side-effect intrinsic to digital filters, corrupting the output signal. In order to minimize this issue, this paper proposes a new method for transient suppression of low-pass, high-pass, band-pass and band-stop IIR filters. The suggested algorithm iteratively adjusts the inner state of the filter until the output signal is considered to have reached its steady state.
