Keyboard Encoder

A keyboard encoder is basically decimal to 8-4-2-1 BCD encoder. The truth table for decimal to BCD conversion can be represented like as follows, From the above truth table it is cleared that, the logical circuit of this keyboard encoder must have 10 input parts (0 to 9) and four output parts. A, B, C … Read more
