True or False Questions (15 points) (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 itto single channel. True or False? (c) A combinational circuit is an example of a logic circuit for digital systems. True or False? dd) 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 flop requires a clock pulse. True or False?

Explanation / Answer

a. The output of NOR gate is High if all of its inputs are Low.
   NOR is exact opposite to OR. OR stands if either of the value
   is high, the result is high.
   So, if all inputs are low, OR will be low, and therefore,
   NOR will become high. So, the answer is TRUE.
b. The function of a multiplexer is to select 1 out of N input
data sources and to transmit it to single channel.
A multiplexer will just select one of several input signals
and will forward that signal t output. So, the answer is TRUE.
c. A combinational circuit is an example of a logic circuit for
digital system.
TRUE. A combinational circuit is a combination of circuits,
whose output depends only on the input signals.
d. The D flip flop is only activated by a negative edge trigger.
FALSE. D flip flops could be either negative edge triggered
or even positive edge triggered.
e. The only difference between a combinational circuit and
a flip flop is that the flip flop requires a clock pulse.
FALSE. For combinational circuits the output is based only
on the input signals, where as for flip flops the output
sometimes also depend on the previous state values.
