Question
A combinational circuit is specified by the following three Boolean functions:
F 1 ( A , B , C ) = Σ ( 1 , 4 , 6 ) F 2 ( A , B , C ) = Σ ( 3 , 5 ) F 3 ( A , B , C ) = Σ ( 2 , 4 , 6 , 7 )
Implement the circuit with a decoder constructed with NAND gates (similar to Fig. 4.19 ) and NAND or AND gates connected to the decoder outputs. Use a block diagram for the decoder. Minimize the number of inputs in the external gates.
