DIGITAL QUASI-EXPONENTIAL FUNCTION GENERATOR

摘要

A quasi-exponential function generator comprising a multistage counter which is clocked at a rate which is a function of the count or value of the counter. The possible counts are divided into fields which are sensed and the clock rate is reduced by a factor of two, as the count changes from one field to a lower field. Each field is further divided into several subfields which are also detected to control the clock rate to vary from subfield to subfield.
