Circuits for Voltage Tuning the Parameters of Chua’s Circuit: Experimental Application for Musical Signal Generation by GUO-QUN ZHONG?, ROBIN BARGARS CWZd

It is well known that Chua’s circuit can exhibit numerous hifiircution phenomena and attractors by tuning one or more circuit parameters. These properties can be used to synthesize sounds with complex freyuenqy spectra ,fbr musical purposes. Investigations of Chua’s circuit for sound synthesis and music composition have produced spec$cutions for tuning multiple circuit parameters to obtain spec$c classes of sounds. This paper presents u multiple control of Chua’s circuit in which euch parameter of the circuit cun be varied by un external control coltage. The design of’ the subcircuits and the experimental results are shown. Programmable computer sqftware wns designed to provide f&t multiple-parameter control elf the anulog Chuu’s circuit,fbr use in music composition and live performunce. The basic circuit discussed in this paper uppeured in a series of’ live music peyformunces at Espo ‘93, Seoul, Korea.
