Question
(a) The output of NOR gate is High if all of its inputs are Low. True or False? (b) The function of a multiplexer is to select 1 out of N input data sources and to transmit it to single channel. True or False? (c) A combinational circuit is an example of a logic circuit for digital systems. True or False? (d) The D flip flop is only activated by a negative edge trigger. True or False? (e) The only difference between a combinational circuit and a flip flop is that the flip Hop requires a clock pulse. True or False?Explanation / Answer
a) True, NOR gate gives high input when the both inputs are low only.
b) False, Multiplexer main function is to select from n input lines and send it through the single output line.
c) True , combinational circuit is example of logic circuit.
d) False, D flip-flops can also be activated by using positive edge trigger.
e) False, Flipflops have memory to store the past output and the combinational circuit doesn't have.
