CS 221 Logic Design 2023 DR.SOHA AHMED EHSSAN 1 Combinational circuits LECTURE 6 2 Remember This chapter includes the most important standard combinational circuits: ◦ Adders, Subtractors, Comparators, Decoders, Encoders, and Multiplexers We will know their internal design and the functionality of each. But, remember our aim is to know how to think to design a circuit 3  2n outputs n-inputs nxm... decoder Decoders A Decoder: ◦ Is a popular combinational logic building block ◦ It converts input binary number to one high output 2‐input decoder ➔ Has four possible input binary numbers ➔ So, it has four outputs, one for each possible input binary number 1 0 0 0 1 1 0 0 0 1 0 0 1 0 1 0 0 0 1 0 4 0 0 0 1  2n outputs n-inputs nxm... decoder Decoders Decoders are called n-to-m line decoders, where m
