Quadrature Counter
April 2021
EN.520.142 Digital Systems Fundamentals
Objectives:
Speed up the cycle counting so that it counts twice per cycle instead of one (see video
demo)
Skills Applied:
Using the SN74HC193N counter and other simple logic gates
Comments:
I use to over-complicate this task until a TA suggested using AND gates with several rising and
falling clock edges. The same concepts also apply to the COMS Imager project.
Scratch work.
Logic flow.
