Lecture 12: Decoders & Encoders - CPS213 Computer Organization I

These flashcards cover key vocabulary terms and their definitions related to decoders and encoders in digital circuits.

Decoder

A device that decodes binary input into a specific output based on the provided binary code.

Encoder

A device that converts input signals into binary codes.

Enable Input

An additional input used to activate or deactivate the decoder.

2-to-4 Decoder

A decoder that takes 2 input lines and produces 4 output lines.

Truth Table

A table that shows all possible input combinations and their corresponding outputs.

Minterm

A product term in boolean algebra that corresponds to a specific combination of variable states.

K-map

A graphical method used to simplify boolean functions.

Combinational Circuit

A type of digital circuit where the output is a function of the current inputs only.

Priority Encoder

An encoder that gives priority to the highest input line when multiple inputs are activated.

(x1, x0)

Input variables used in binary encoding/decoding.

(O0, O1, O2, O3)

Output lines corresponding to a 2-to-4 decoder.

Low Activated Enable

An enable signal where the decoder is activated when the enable input is low (0).

Full Adder

A circuit that adds three input bits (two significant bits and a carry-in bit) and produces a sum and a carry-out.
