Basics of
Digital
Systems
Written by: Ram Harshith
,Introduction to Digital
System:
To understand the operation of each digital module, we require
the basic knowledge of digital circuits and their logical function.
We use HDLs to describe and simulate the digital circuits.
Digital systems manipulate discrete quantities of
information that are represented in binary form.
Binary means two-valued:0 or 1.
,Binary Numbers:
Binary means 2-ary.
Binary numbers refers to 0 and 1.Base=2 Ex:(1001)2
These two are the symbols recognized by most digital systems.
In general, symbol 0 denotes "off" or "False" and symbol 1
denotes "on" or "True".
Computers mostly uses binary because of transistors and diodes
used in circuits.
Transistors acts as "ON" switch when voltage is "High" and
"OFF" switch when voltage is "LOW".
, 0=0
1=1
Some 10=2
binary 11=3
number 100=4
s to 101=5
decimal 110=6
111=7
: 1000=8
1001=9
