Abstract
A method and apparatus is disclosed for determining the velocity of a document over a fixed distance of travel. Sensing means are provided for generating signals which are used in determining the value of the time the document requires to move over the fixed distance. Using terms of a Taylor series expansion of the velocity equation, a value of the velocity is determined utilizing digital elements requiring only multiplication and addition operations. The elements include a digital multiplier and accumulator together with a plurality of storage devices which utilize the value of the time together with a plurality of predetermined constants to determine and output the value of the velocity to a display which displays the velocity in numerical form.
