Abstract
Delayed mixing is a problem of theoretical interest and practical importance, e.g., in speech processing, bio-medical signal analysis and financial data modelling. Most previous analyses have been based on models with integer shifts, i.e., shifts by a number of samples, and have often been carried out using time-domain representation. Here, we explore the fact that a shift t in the time domain corresponds to a multiplication of exp(-iwt) in the frequency domain. Using this property an algorithm in the case of sources
