Abstract
In order to provide an apparatus and method generating chaotically behaving signals or data, a plurality of delay elements 10 to 14 are connected in series, and an output of the foremost delay element 10 is supplied to a nonlinear function element 30, while outputs of the other delay elements 11 to 14 are supplied to coefficient elements 41 to 44, respectively. The outputs of the nonlinear function element 30 and coefficient elements 41 to 44 are summed at an adding element 50, and the resultant sum is fedback to the foremost delay element 10. Initializing elements 20 to 24 release their respective initial values at one time to thereby initiate the operation. At an appropriate period of time .DELTA.t, the delay, nonlinear operation, coefficient multiplication, and addition are repeated.
