My last column introduced the concepts underlying BCD (binary-coded-decimal) representations. In particular, we considered unsigned versus 10s-complement versions of BCD numbers. In this column we are ...
Most of us can do simple math in our heads, but some people just can’t seem to add two numbers between 0 and 3 without using paper, like [Aliaksei Zholner] does with his fluidic adder circuit built ...
How do you create a full adder using nand gates? A Full-adder circuit adds three one-bit binary numbers (A, B, Cin) and outputs two one-bit binary numbers, a Sum (S) and a carry (Cout). It is usually ...
