A linear-phase IIR filter for audio signal interpolator

Krzysztof Sozański

Open publisher page 5 citations

Abstract

In the paper infinite impulse response (IIR) digital filters with linear-phase (LF IIR) for audio signal interpolator are discussed. This article presents the causal realization of LF IIR and especially the realization of LF IIR filter with overlap is considered. As the LF IIR filters are an alternative for ordinary finite impulse response (FIR) filters, a comparison of a particular design of FIR and LF IIR filter is made. There are also compared realizations of signal interpolators using FIR filter and LF IIR filter.
