Logic gates can be combined to perform any computation. There are millions of them in a computer chip. But let’s see a very simple application of the AND gate. At the left is a schematic for an ...

The schematic from the very first test shows the slight modifications [Dr. Cockroach] made to incorporate light into the logic gate using a 910 Ohm, output LED, and an LED and LDR in parallel.

Logic gates are circuits with electronically controlled switches that combine digital signals according to Boolean algebra. In binary math, bits have only two possible values: 0 (off, false) and 1 (on ...

From the logic diagram of Figure 7.23(a), , that is, the logic diagram represents an XOR gate implemented with NAND gates. The timing diagram for the output C is shown in Figure 7.24. Figure 7.24: ...
