ABSTRACT:
A system for accurately digitizing a signal from a high density optical tachometer using a psuedo zero-crossing detector for subsequent use in a speed measuring device. An added enhancement of the system is the ability to double the frequency response of the input signal to thereby provide a more sensitive indication of incremental speed changes.
