Digital Generation of a Nonlinear Time-Base
J.J. Hill · IEEE Transactions on Instrumentation and Measurement · 1978
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.
