AI Thread Summary
The discussion focuses on building a circuit using two full adders to sum two 2-bit numbers, x0x1 and y0y1, producing a carry output (C) and a sum output (S0S1). The user is familiar with constructing truth and Karnaugh tables, as well as individual full adder circuits. The main challenge lies in chaining the outputs of the two full adders while incorporating a clock cycle. The clock serves as an input for the first adder, with its carry output feeding into the second adder, which generates the final result. This approach is essential for achieving the correct summation of the two 2-bit numbers.

which produces a sum of 2 bit numbers x0x1 y0y1
the output is C (carry)
S0S1

the problem is i know how to build a truth table and a KARNO table
and even how to build this circuit

i know how to build a full adder circuit

the problem is i don't know how to build this task using 2 full adders

Chain the outputs with the clock cycle.


In English, the clock is an input, for adder A, and itz carry is the input for adder B which holds the final solution.
