Calculation of the transient response of lumped linear systems from their frequency response

In the design of systems by frequency-response methods, it is frequently necessary to evaluate the transient response corresponding to a given frequency response. The program presents a method of performing the calculation which gives improved accuracy over other methods due to a new form of approximation of the asympototic behaviour of the frequency response and which is in a form suitable for implementation on a digital computer. An ALGOL program for the calculation is included, and an example of its use is presented.
