**Frequently Asked Questions**

**Q1: What is digital logic design?**

A1: Since digital logic designers build electronic components which use both electrical and computational characteristics, the design is foundational to the fields of electrical and computer engineering. Logical function, power, current, user and protocol inputs are some of the characteristics of digital logic design. It is also used to develop hardware which processes user input and system protocol.

**Q2: Why the digital logic design used for?**

A2: Digital logic design are used to design electronic devices, circuits, logic gates and computer chips.

**Q3: What are the different logic gates?**

A3: AND, NAND, OR, NOR, NOT, XOR are some of the logic gates. These gates are built using transistors. AND & OR gates need 3 transistors where are NAND & NOR gates require 2 transistors.

**Q4: What are career opportunities in digital logic design?**

A4: Since everything is becoming digital now, there is a high demand for the digital logical designers. Though the subject is easier that it appears to be, there is a high competition to be placed in the preferred job. Applicants’s tenacity, ability to adapt easily to new situations, social skills, quick learning are some of the qualities which a recruiter might be looking for apart from the great marks from degrees. MATLAB, VERILOG HDL, CADENCE, LINT are looking for more digital logic designers

**Q5: What does a digital logic designer do?**

A5: Digital logic designer designs digital systems for test and manufucturability, hardware implementation, simulation etc. Basically he/she designs computer parts which makes the computer work.

**Q6: What are the ways in which logical functions can be expressed?**

A6: Different ways in which logical functions can be expressed are

- Logical expression
- Truth table
- Graphical form

**Q7: What are the integration levels of logic chips?**

A7:

Integration Levels |
|||

SSI | MSI | LSI | VLSI |

Small scale Integration | Medium Scale Integration | Large Scale Integration | Very Large Scale Integration |

First introduced in late 1960s | First introduced in late 1960s | First introduced in early 1970s | First introduced in late 1970s |

1-10 gates involved | 10-100 gates involved | 100-10000 gates involved | More than 10000 gates involved |
