with some explaination please

for the following questions: C Q1. State True or False for the following questions: (5 x 3 15 points) a. Edge-triggered flip-flops can be identified by the triangle on the clock input. b. When the S and the R inputs are both HIGH the output of an S-R NOR latch will always be 0. c. A counter has a specified sequence of states, but a shift register does not. d. J-K Flip-Flop can be made toggle when J-0 and K-0. e. A positive edge-triggered flip-flop changes states with a HIGH-to-LOW transition on the clock input.

Explanation / Answer

a).True

The triangle is known as the dynamic input indicator.

b).True

Hence generally state with S=1 and R=1 is called as 'Not allowed' state.

c).True

A counter has a specified sequence of states excluding in a few particular implementations

d).False

It toggles only when both Jand K are equal to 1 i.e J=1 , K=1

e).Flase

Negative edge triggered changes states with a High-to-Low transition on the clock input , but not positive edge triggered flip flop(i.e from Low-to-High transition).
