What do you understand by term
āDigital Logic Designā
- (^) What is digital?
- (^) What is logic?
- (^) How to design logic?
Take simple Example of a clock
- (^) We have both analogue and digital clocks.
Digital v/s Analogue Analogue Digital
- Analog signal is a continuous signal which represents physical measurements.
- Digital signals are discrete time signals generated by digital modulation
- Denoted by sine waves (^) ā¢ Denoted by square waves
- Human voice in air, analog electronic devices.
- Computers, CDs, DVDs, and other digital electronic devices.
- Less immune to errors, distortion and delays
- Highly immune to errors, distortion and delays
What do you understand by term āDigital Logic Designā
- (^) What is Logic?
- (^) A logic is a predefined way to understand things or to perform tasks. Take daily life examples of logical tasks. - (^) How can you solve math? - (^) How can you drive car?
What do you understand by term
āDigital Logic Designā
- (^) How can a computer or machine can make these logics?
- (^) This is what this course is all about.
What do you mean by a Number?
- (^) Say, what is meant by digit ā2ā or digit ā3ā?
- (^) A number is actually a symbol which is used by us to solve our daily life problems.
What is a system of a number?
Take simple Example Of a clock
- (^) Suppose its 12-pm now. What will be the time after 14 hours?
Take simple Example Of a clock
- (^) A clock is a number system, which has hours from 1 to 12, what happens if we have more than 12hr?
- (^) For example, what will b the time after 24hr from now on?
- (^) Surely clock has no 24 digit on it, so we need to convert it, so that we can have any digit between 1-12.
