Title :
Digital Generation of a Nonlinear Time-Base
Abstract :
A method of generating nonlinear time-bases is described. The approximation may be either step or piecewise linear and involves using a READ-ONLY memory as a look-up table to store digitally the shape of the required function. The case of a logarithmic time-base is considered in detail.
