NOR Gate can be used  to perform  the operation of AND, OR and NOT Gate

► FALSE

► TRUE

NAND gate is formed by connecting                       

► AND Gate and then NOT Gate

► NOT Gate  and then AND Gate

► AND Gate  and then OR Gate

► OR Gate  and then AND Gate

Consider A=1,B=0,C=1. A, B and C represent the input of three  bit NAND gate the output of the NAND gate will be                                                       

► Zero

► One

► Undefined

► No output as input is invalid

The operation of J-K flip-flop is similar to that of the SR flip-flop except that the J-K flip-flop

► Doesn’t have an invalid state

► Sets to clear when   both J = 0 and K = 0

► It does not show transition on change in pulse

► It does not accept asynchronous inputs

                       is one of the examples  of asynchronous inputs.

► J-K input

► S-R input

► D input

► Clear Input (CLR)

The                          input overrides the                 input

► Asynchronous, synchronous

► Synchronous, asynchronous

► Preset input (PRE),  Clear input (CLR)

► Clear input (CLR), Preset input (PRE)

In                  outputs depend only on the combination of current  state and inputs.
