7448 seven segment display!

A circuit converts a 4 bit binary input into a seven segment display output.

I have to use a 7448 and simulate the circuit using either multisimm or proteus.
also setting up a word generator to produce a count on the seven segment display from 0 to 9.
Attach a logic analyser to the output to display the count in timing diagram form. the

Connecting form the 7448 to the seven segment is not a problem but the rest I do not have a clue where to start is there any information that you or any body could share with me on this?

Regards

Brian

You might as well get the terminology correct - a 7448 is a BCD to 7 segment decoder. It has active high outputs, so it works with common cathode displays.
also setting up a word generator to produce a count on the seven segment display from 0 to 9.
A BCD counter would be the thing to use.

7446, 7447 & 7448 are specific to the displays, if you Google the part number with the word circuit after it you'll find a multitude of examples as you will with their individual datasheets which are also often filled with simple circuits &/or references to application notes.
