Q.1.

A one-shot is a special type of multivibrator, which must be triggered to produce each output pulse.

Q.2.

Edge-triggered flip-flops can be identified by the triangle on the clock input.

Q.3.

Multivibrators must be level-triggered.

Q.4.

The 555 timer can be used in either the bistable mode or the monostable mode.

Q.5.

A D-type flip-flop is constructed by connecting an inverter between the Set and Clock terminals.

Q.6.

J-K flip-flops are often used as switch debouncers.

Q.7.

When the S and the R inputs are both HIGH the output of an S-R NOR latch will be unpredictable.

Q.8.

The J-K flip-flop eliminates the RACE state when both the J and K inputs are HIGH.

Q.9.

Pulse-triggered flip-flops are identified by a bubble on the Q output terminal.

Q.10.

When using master-slave flip-flops, the data is entered into the flip-flop on the leading edge of the clock, but the output does not change until the trailing edge of the clock.
