00:00Digital and Analog System
00:03Analog System
00:06Analog system is defined as
00:09any physical quantity
00:11which varies
00:13continuously with respect to time
00:16continuous value in analog system
00:19graph is like as a web
00:22graph is not a web
00:24and respect to time
00:26analog system is a web
00:28the 0 plus 5 volt
00:30then minus 5 volt
00:32example of analog system is
00:35Amplifier
00:37was radio etc
00:39Digital system
00:41Digital system is defined as
00:43any physical quantity
00:45having
00:47discrete digital value
00:49or data
00:51Example is
00:52digital was
00:54calculator
00:55blood pressure machine
00:57thermometer etc
01:01In digital system
01:03discrete value or digit
01:05or finite sequence
01:07there is no wave like graph
01:10Advantages of digital system
01:12Digital systems are easy to design
01:15because they do not require sound engineering and mathematical knowledge
01:19normal

01:22region
01:23uses only switching circuit
01:25like
01:26assembling a computer

01:28and computer
01:29assemble
01:30and easy
01:31thus parts
01:32assemble
01:33easy to store
01:34heavy and bulk data
01:36heavy and bulk data
01:38store
01:39easy
01:40processing of information
01:41easy
01:42they provide mass more powerful process
01:45and calculation speed
01:47in digital system
01:49less affected by noise
01:51like sound
01:52elliptic field
01:53magnetic field etc

01:59digital compass
02:00and analog compass
02:01better modularity
02:03easy to assemble
02:04various
