Program Plan Intro

a)

Non-return-to-zero method:

  • It is one of the data encoding technique. This method has binary code to represent the significant notation.  The binary number “1” represents the positive voltage and “0” represents the negative voltage.
  • Each bits occupies certain space of the storage disk, these speck is called bit cell.

Program Plan Intro

b)

Non-return-to-zero-invert method:

It is similar to NRZ. The difference is that the transition depends on the current state for every “1” and state “0” has no transition provided in signal.

Program Plan Intro

c)

Manchester code:

It is an encoding method used in the transmission of data which provides the transition for each bit whether it is one or zero. It is otherwise called as phase modulation method (PM).

  • The signal transition is “1” when the transition signaled to “up”.
  • The signal transition is “0” when the transition signaled to “down”.

Explanation of Solution

d)

Frequency modulation:

It is similar to the Manchester encoding method. The transition is provided in every bit sequence. The additional transition is provided in middle of each cell for every “1”...

Explanation of Solution

e)

Modified frequency modulation:

It is an improvement over the frequency modulation coding. The transition happened at the boundaries between the cells with two consecutive zeros...

Program Plan Intro

f)

Run-length-limited code:

It is an encoding method which translates the character code like ASCII or EBCDIC into code words. The function RLL (d, k) allows a minimum of “d” and maximum of “k” consecutive zeros which are appear between any pair for consecutive ones.
