Question

How do you draw a digital logic circuit based upon a truth table with 4 inputs and 2 outputs?

Answer 1

you have truth table four inputs and 2 outputs. minimise and draw for each output by drawing K-maps. you can also use boolean algebra for getting the equation of outputs in terms of inputs. then realise this equation using NAND or NOR gates.

Answer 2

Depends on the table.

If you just want to draw the table, just make 6 columns and put down the ones and zeros.

If the numbers are fairly random, take the table and burn a ROM (4 addresses by 2 bits) and put the data into it.

Worse case, use a bunch of diodes, and two gates as buffers.
