The sequential circuits consists of

• Combinational logic as well as memory elements

• Combinational logic only

• memory elements only

• Logic Gates only

The example of sequential circuit is

• Multiplexers

• Decoders

• 7 Segment display

• Counters

When the output of a sequential circuit depends on the present input as well as previous output states, then the circuit is called

• Moore machine

• Mealy Machine

• Sequential circuit

• Combinational circuit

A n bit shift register cannot be used as

• Module n counter

• Module 2n counter

• Serial to parallel conversion

• parallel to serial conversion

Generally shift register is constructed by using

• T FF

• SR FF

• D FF

• JK FF

The number of flip-flops are required for mod-5 counter

• 1

• 2

• 3

• 4

In design a counter circuit, the most commonly used flip-flop is

• SR FF

• D FF

• JK FF

• Latch

The minimum number of flip-flops required for a synchronous decade counter is

• 1

• 2

• 3

• 4

What is the modules of 5-bit ripple counter

• 16

• 32

• 64

• 128

A mod-2 counter, followed by a mod-5 counter is

• mod-5 counter followed by a mod-2 counter

• mod -9 counter

• mod-11 counter

• decade counter
