Introduction to Digital System Design Notes

Digital system design pdf: An advanced framework is a framework that accepts computerized signals as data sources, measures them, and produces computerized yield signals. An advanced sign is a sign where discrete advances are used to speak to data and change esteems just at discrete (fixed) time stretches. Interestingly, simple signs have “consistent” varieties in signal sufficiency over time. At a given moment of time, a simple sign has limitless potential qualities. A computerized signal has discrete sufficiency and time. Computerized frameworks are helpful in the regions of signal handling (i.e., sound, pictures, discourse, and so forth), registering, correspondence, and information stockpiling, among others.

Advanced frameworks are so ordinary in this day and age that we will in general miss seeing them. Practically all electronic frameworks are halfway or absolutely carefully based. Obviously, true signals are altogether simple, and interfacing to the outside world requires the transformation of a sign (data) from computerized to simple.  Notwithstanding, straightforwardness, flexibility, repeatability, and the capacity to deliver hugely and mind boggling (all things considered) frameworks financially make them brilliant for handling and putting away data (information).

FAQs on Digital System Design Notes

Question 1.
What is the difference between Latch and Flip-flop?

The difference between latches and Flip-flop is that the latches are level triggered and flip-flops are edge triggered. In latches level triggered means that the output of the latches changes as we change the input and edge triggered means that the control signal only changes its state when goes from low to high or high to low. Latches are fast whereas flip-flop is slow.

Question 2.
What is the binary number system?

The system which has a base 2 is known as the binary system and it consists of only two digits 0 and 1.

For Example: Take decimal number 625

625 = 600 + 20 + 5

That means,

6×100 + 2×10 + 5

6 ×102 + 2×101 + 5×100

In this 625 consist of three bits, we start writing the numbers from the rightmost bit power as 0 then the second bit as power 1, and the last as power 2. So, we can represent a decimal number as

∑digit × 10corresponding position or bit

Here 10 is the total number of digits from 0 to 9.

Question 3.
What are the applications of the octal number system?

The applications of the octal number system are as follows:

  1. For the efficient use of microprocessors.
  2. For the efficient use of digital circuits.
  3. It is used to enter binary data and display information.

Question 4.
What are the advantages and disadvantages of the K-Map Method?

The advantages of the K-Map method are as follows-

  1. It is an excellent method for simplifying the expression of up to four variables.
  2. For logical simplification, it gives us a visual method.
  3. It is suitable for both SOP and POS forms of reduction.
  4. It is more suitable for classroom teachings on logic simplification.

The disadvantages of the K-Map method are as follows:

  1. It is not suitable when the number of variables exceeds more than four.
  2. For Computer reduction, it is not suitable.
  3. We have to take while entering the numbers in the cell-like 0, 1 and don’t care terms.
