EE 2301 S 2010 INTRODUCTION TO DIGITAL SYSTEMS DESIGN HOMEWORK #7 (20 pts) Due April 20, 2010 1. Problem 15.3 from the text book. 2. Design sequential code converter (Mealy-style) that receives decimal digits encoded as Excess- 3 inputs, and generates corresponding BCD outputs. Excess-3 inputs are received sequentially, least significant bit first, and the network should reset after receiving 4 binary inputs. This converter is similar to design example shown on p.1 Lecture Set 6, except that its input (X) and output (Z) are interchanged. Show the transition diagram, reduce the number of states if needed, and then implement this network using D flip-flops and external gates. 3. Consider a similar problem of designing sequential code converter for converting BCD-coded inputs 1 to 9 to Roman numbers, according to Table shown below. The network should reset after receiving 4 binary inputs. Explain whether it is possible to design such a code converter. You
