Abstract

This paper describes the development of a system for the measurement of power in the audio frequency range. Flexible units operating with a strategy based on the evaluation of rms quantity by a thermal method have been constructed. For each unit of the set-up, measurements and a preliminary characterization have been performed and estimation of the uncertainty will be discussed.
