ANORDNUNG ZUR UMWANDLUNG EINES ELEKTRISCHEN SIGNALS IN EIN AKUSTISCHES SIGNAL ODER UMGEKEHRT UND EIN NICHTLINEARES NETZWERK ZUR ANWENDUNG IN DIESER ANORDNUNG.

摘要

An arrangement for converting an electric signal into an acoustic signal (y/t) or vice versa, comprises an electroacoustic transducer (2) and means (3) for reducing distortion in the output signal of the arrangement, which distortion is caused by the electroacoustic or acoustoelectric conversion performed by the transducer. The means comprise a non-linear network (3', 3'' or 3''' in FIGS. 3; 43', 43'' or 43''' in FIG. 4). The non-linear network is arranged for reducing non-linear distortion by compensating for at least a second or higher order distortion component in the output signal of the arrangement. The network may comprise at least two parallel circuit branches (15a, 15b in FIG. 3; 47a, 47b in FIG. 4). At least one of the circuit branches (15b in FIG. 3; 47b in FIG. 4) compensates for non-linear distortion of the second or higher order.
