When two or more inputs are active simultaneously, the process is called:

• first-in, first-out processing

• priority encoding

• multiplexer

• priority decoding

Which one of the following digital logic blocks is the most suitable for implementing this function?

• Full adder

• flip flop

• Priority encoder

• Multiplexer

The BCD adder to add two decimal digits needs minimum of

• 6 full adders and 2 half adders

• 5 full adders and 3 half adders

• 4 full adders and 3 half adders

• 5 full adders and 2 half adders

One major difference between a NAND based S'-R' latch & a NOR based S-R latch is

• The inputs of NOR latch are 0 but 1 for NAND latch

• The inputs of NOR latch are 1 but 0 for NAND latch

• The output of NAND latch becomes set if S'=0 & R'=1 and vice versa for NOR latch

• The output of NOR latch is 1 but 0 for NAND latch

In a NAND based S'-R' latch, if S'=1 & R'=1 then the state of the latch is

• No change

• Set

• Forbidden

• Reset
