Hexadecimal-to-Octal Converter with Display

Input: 1-digit Hexadecimal Number represented by 16 input points
Output: 2-digit Octal Number represented by 8 output points

Logic Function

The circuit will convert the hexadecimal input into its octal equivalent. Both the input and output must be displayed using a seven-segment display. Note: For the number 6 the 'a' LED with light and for the number 9 the 'd' LED will light.

When you say input and output points, do you mean that there is a data line for each possible value?

Its also worth noting that for a single digit hex number 0-F, the octal representations will be 00-17 (the high digit will only ever be 0 or 1)

almost done with my project, my only problem is that i dont know how to display A-F using 7 segment display.. can u help?

For 4-to-7 hexadecimal decoding the convention is that the B & D digits are displayed as lower case.

0 1 2 3 4 5 6 7 8 9 A b C d E F

Find a binary to 7 segment decoder that decodes 10 to 15 as A to F.

Here is one which decodes all states, but not as recognisable letters.

Here is one which outputs 0-9, A-F.

Here is one which outputs 0-9, A-F.

Since this is a homework assignment, do you suppose the professor gives extra credit for finding a commercial chip? Or is designing a segment decoder from scratch part of the assignment? My guess is the learning experience demands the student build the truth table for each segment, construct the seven Karnaugh maps, do the minimization, and then layout the gated decoder circuit. That way the student will fully appreciate having the option to use a commercial chip for a real project.
