Digital Logic Circuits

Yes You Can

You can build your own logic circuits. You can buy chips with 4 or more NAND or NOR gates on them and wire them up. You can experiment on a 'bread board' like the one I demonstrated, or you can solder then to boards for more permanent productions. You need to supply about 5 volts for most chips. The output side of the chips to not supply much power so you need to learn to amplify this with a transistor (a small npn type is usually all that is required). Remember when you do the simulations that they correspons to real chips and circuits that you could build.

experience 7

Turn to page 69 in the lab book and do all of lab experience 7. Note that the + means 'or' and the * means 'and. Why?
Turn to Page 77 and do all of lab 8.
