Study Notes
Combinational Circuits
- This chapter covers important standard combinational circuits, including Adders, Subtractors, Comparators, Decoders, Encoders, and Multiplexers.
Decoders
- A Decoder is a popular combinational logic building block that converts input binary numbers to one high output.
- A Decoder has n inputs and 2^n possible outputs.
- A 2-input Decoder has four possible input binary numbers, resulting in four outputs, one for each possible input binary number.
- Decoders are referred to as n-to-m line decoders, where m = 2^n.
