This article deals with the problem of signals used for driving transducers with the direct digital-to-analog conversion, which are sometimes called “Digital Loudspeakers”. Many claim elementary transducers, which transmit bit signals, should have ideally flat impulse response, imposing a very strict demand on them. In this article analysis of transducers in the field arrangements acting as signal filters is given. Various types of transducer transfer functions are modeled and their influence on digital (rectangular) signal is shown. As a result, types of transducer transfer functions for usage in digital loudspeakers are discussed.
