CHIP XOr { IN c, f; OUT out; PARTS: //XOR == (c Or f) and (NOT(c and f)) == (c Or f) and (c Nand f) == Not[(c Or f) Nand (c Nand f)] // First stage: (c Or f) // c Or ...

Logic gates process data and generate outputs using Boolean algebra and truth tables (Figure 1) to define operations for all binary input combinations: 0 (false, low) and 1 (true, high). Figure 1. A ...

Switching algebra is easily visualized using switches since there are only two values: on and off, or true and false. In digital systems we represent these as 1 and 0, respectively. There are only two ...

nand (not_a, a, a); // not_a = a NAND a = NOT a nand (not_b, b, b); // not_b = b NAND b = NOT b // OR gate using NAND (NAND of inverted inputs) $strobe($time," a=%b ...

This is going to be a column that’s divided into three sections. It’s based on a question that a student posed in the EEWeb forums, and he also sent it directly to yours truly. The core of this ...
