Abstract
The letter describes two methods for the construction of digital-integrator transfer functions with an ideal phase characteristic. The first is based on the approximation of the function ln z by means of continued fractions, and the second consists in the approximation based on the principle of the impulse-response invariance. The transfer functions can be approximated to in both cases by nonrecursive transfer functions in the bilateral z transformation.
