Convention Paper

A New Technique for Fast Response Measurements Using Linear Swept Sine Excitation

Authors: Struck, Christopher J.; Biering, C. Henrik

AES Convention 90 · Paper 3038 · February 1991

Abstract

Response measurements performed using Time Delay Spectrometry utilize a linearly swept sinusoidal excitation signal. Increasing the sweep rate in TDS can result in serious errors in the measured response. A new measurement technique is introduced which allows faster sweep rates to be used than with traditional TDS measurements. This technique enables the correct measurement of the complex time-selective frequency response as well as providing flexibility in the application of windowing functions.
