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.
Describe
the function of shift register.
The function of the shift register is to store
binary words.
Explain
the term : Loading of register
Loading of register
The loading of register
means setting or resetting of individual flip flop.
Which is
the simplest type of register?
Buffer register
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.
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.
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.
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.
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.
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.
