it is the introduction about signals

2.  As you are informed that the work with digital
domain is efficient then analog domain.
 As you know that all real life signals are
analog.
 So in this slide we will learn. How we can
process it by using digital system?
 I am going to explain the whole
arrangement.

3.  How it will works?
 We also try to find the arrangement which
we have to learn in this course?
 This is the course of Digital Electronics and
Design.
 From this slide each and every thing is
important and you should practice it.
 Previous slides are the basics.
 Lets Start

4.  We have two analog interface.
 First one is the input interface.
 Second one is the output interface.
 There will be a transducer and an anti-
transducer .
 There is also a digital system.
 Lets have a look at diagram.

6.  Lets have an analog signal converted into
digital signal.
 Transducer send multi-bit stream to the
digital system.
 Digital system can b a computer calculator or
any measuring instrument.
 The signal is again converted back to the
analog and you have output.

7.  We will learn about the digital system.
 Remember we are not going to learn
computer calculator etc.
 Digital system is made of sub-systems.
 These sub-systems are made of Modules.
 Modules are made of basic units.
 I am not going further but you can take basic
units as logic gates.

Basic Units(Logic gates)

9.  Know you know some thing about the digital
systems.
 We have to learn the basic units i.e. logic
gates.
 Remember that these gates have some
input.
 They are made of circuits resister capacitor.
 According to their arrangement a specific
logic is set.
