A block diagram of 3:8 decoder (3 input lines and 8 output lines) is shown in Figure 2. To implement the optical 3:8 decoder, we use TOAD-based optical switches, namely s 1 to s 12 as shown in Figure ...

A 3 to 8 decoder has three inputs (A, B, C) and eight outputs (D0 to D7). Based on the 3 inputs one of the eight outputs is selected. Truth Table. Logic Diagram. Block diagram. Encoder: The ...
