So, what can we do?
Lets make it
FUn ! :-) :-)
truth table for
3-bit binary signal
Sum of binary weights should be equal to one. (1)
General formula for binary weights associated with LSB:
Time for a question?
Answer: 1/15 , 2/15, 4/15 and 8/15
How does it work?
- Convert LSB(s) to their analog value. ( 001 = 1, 010 =2)
- Sum up these analog values.
simple enough, right? ;-)
"The voltage between the ends of the circuit is equal to the total current entering the supernode divided by the total equivalent conductance of the supernode".
Apply the formula for the circuit above.
Lets continue with ladder networks...
ladder output voltages
Now, we bring in the
Any idea why?
Obvious, isn't it!
Relax with recap!
AND, WE'RE DONE!
But before that,
What's the basic difference between analog and digital signals?
Relax! You don't have to answer this one.
