advantages of digital approach
-
after noise is added, can still determine the logic values
component values in digital circuits do not need to be as precise as in analog circuits
complex digital logic circuits can be produced economically
- analog signal
- each amplitude in a continuous range has a unique significance
-
basic logic circuit concepts
-
advantages of digital approach
positive vs. negative logic
digital words
transmission of digital information
- bit
-
single binary digit
- byte
- word consisting of 8 bits
-
digital signal
- only a few restricted ranges of amplitude are allowed, and each amplitude in a given range has the same significance
-
logic values
-
binary signals take on amplitudes in only two ranges, and the information associated with the ranges is represented by logic values 1 or 0
- nibble
-
a four bit word
-
positive vs. negative logic
-
positive: higher amplitude: 1
lower amplitude: 0negative: higher amplitude: 0
lower amplitude: 1 -
representation of numerical data in binary form
-
in binary form we are able to convert numbers of base 10 to a base 2 number system
