Explain
the term : Single bit register and register
|
|
Single bit register
- It is a flip
flop which can store only one bit of data i.e. either 1 or 0.
Register
- It is a set of
flip flops which is used to store binary data.

How
data is transferred in the shift register?
|
|
Data Transfer
through Shift register
- The data can
be transferred in the shift register in the serial form or parallel form.
- There is only
one bit of data can be transferred from one device to another device at a
time in the serial form whereas all bits of data can be transferred
simultaneously from one device to another in the parallel form.

Describe
the difference between shift register and counter.
|
|
Shift register
- It is used for
storage and transfer of digital data.
- It has no
specific sequence of states.
Counter
- It has
specific sequence of states.
|
4
|
Describe
the function of shift register.
|
|
The function of the shift register is to
store binary words.
|
5
|
Explain
the term : Loading of register
|
|
Loading of register
- The loading of
register means setting or resetting of individual flip flop.
|
6
|
Which
is the simplest type of register?
|
|
Buffer register
|
7
|
Describe
the methods of data transfer from the input to the output in the shift
register.
|
|
Data Transfer in the
shift register
- Serial in
serial out
- Parallel in
parallel out
- Serial in
parallel out
- Parallel in
serial out
|

|
Describe
the meaning of SH and LD at the input of the shift register?
|
|
SH and LD
- The input
signal SH ( shift ) and LD ( load ) allows the data is entered parallel form
into the register and data to be shifted out serially from output terminal Q.
|
9
|
Which type
of flip flop is used in the shift register in order to avoid timing problems?
|
|
The edge triggered or master slave flip flop
is used in order to avoid timing problems in the shift register.
|

|
Explain
the term : Bi – directional shift register
|
|
Bi – directional shift
register
- It is a shift
register in which the data bits can be shifted either left to right or right
to left.
|
11
|
What
is universal shift register?
|
|
Universal shift
register
- It is a bi –
directional shift register in which the input as well as the output can be
either in serial form or parallel form.
|
12
|
At
which condition the data bit do not shift in the universal shift register?
|
|
The data bits do not shift in the universal
shift register when the both master control inputs are either LOW or HIGH.
|
13
|
What
is Dynamic shift register?
|
|
Dynamic shift
register
- It is a shift
register in which the shifting of bits from one stage to the next stage and
the output of the last stage to the first stage circulate through register
under a control of clock pulse.
|
14
|
Describe
the main difference between static and dynamic shift register.
|
|
Static shift
register
- It is a
register in which the data bit loaded once, the contents of the each element
in the register remains the same.
Dynamic shift
register
- It is a shift
register in which the shifting of bits from one stage to the next stage and
the output of the last stage to the first stage circulate through register
under a control of clock pulse.
