A full-adder is more generally known as a (3,2) counter, in that itadds three bits, producing a two bit result (sum and carry). A (4,3) counter sumsfour-bits, producing a three-bit result, and a (10,4) counter sums ten-bits, producing afour-bit result.
(a) Draw a diagram showing how to connect a full-adder and two half-adders to form a (4,3) counter.
(b) Draw a diagram showing how to connect full-adders and half-adders to form a minimal delay (10,4) counter.
