6
|
How many numbers of
possible inputs does the 4 – bit DAC consists of?
|
16 inputs

|
Explain the
statement ‘The output of the DAC is pseudo analog quantity.’
|
The output of the DAC is not true analog
quantity because it can take specific values. It is actually digital
therefore the output of the DAC is pseudo analog quantity.
