120 Progress of Theoretical Physics Supplement No. 99, 1989 A New Type of Intermittency in an Electronic Circuit

An intermittency which has a different origin from the Pomeau-Manneville types is studied in a coupled nonlinear LCR circuit. This type of intermittency has a close relation to the multiplicative noise process. The electronic circuit is made up of inductors, resistors and capacitor diodes. An experimental study is done in this system. The results are compared with those of a phenomenological theory based on the multiplicative noise process. More· over, a numerical calculation is also carried out on the equations for the present circuit with observed nonlinear characteristics of diodes. Satisfactory agreement between the exper· imental and calculated results is obtained
