DISTORTION IMMUNITY OF MLS-DERIVED IMPULSE RESPONSE MEASUREMENTS
Chris Dunn, M.O.J. Hawksford
Abstract
Maximum length sequences (MLS) are becoming widely used as an accurate method of deter-mining the t rnpque response of audio transducers Although MLS techniques offer an enhanced immunity to noise and distortion compared to periodic impulse testing, non-linearity in the measurement chain .rtill results in t'mpque response errors. This paper examines the nature of such error: within typical measurznrent environments.
