Analog Computer Generation of Bessel Functions of Arbitrary Order

This paper presents a method for analog computer generation of Bessel functions of arbitrary order. It is shown at the beginning that the direct analog implementation of Bessel differential equation leads to rather inaccurate mathematical models. These inaccuracies are caused by the necessity of dividing nonzero quantity by zero. Based on these considerations this paper suggests a new approach which, transforming the given mathematical model, overcomes the mentioned disadvantages and permits accurate generation of Bessel functions of arbitrary order.
