1. Homework 2 Due 28 th May 2014

2. Implement This Function using 1)a 3-to-8 Line Decoder (with OR gates) 2) a 3-to-8 Line Active Low Decoder (with NAND gates) 3)only 1-to-2 Line Decoders (with NOR gates) Note: For 3 you’ll have to use Decoder Trees Marks = 3 + 4 + 5

3. F = A’B + ACD Implement This Function using 1)a 4-to-16 Line Decoder (with NOR gates) 2)a 4-to-16 Line Active Low Decoder (with AND gates) 3)only 3-to-8 Line Active Low Decoders (with NAND gates) Note: For 3 you’ll have to use Decoder Trees Marks = 3 + 4 + 5
