1. Sequential Circuits Problems(II) Prof. Sin-Min Lee Department of Mathematics and Computer Science Algorithm = Logic + Control

3. A Gray Code is a binary sequence where only 1 bit ever changes between adjacent values in the sequence. Gray codes can easily be produced from Karnaugh Maps simply by tracing a single looped path which enters each location in the Karnaugh Map exactly once. which gives the Gray Code

8. BCD Counters A special case of an arbitrary sequence counter is that of a BCD (Binary Coded Decimal) counter. This counter counts in decimal from 0000 2 to 1001 2, and then sets itself back to 0 again.
