Problem (1)
Willy Nilly needs your help. He has been given a D/A board by Dr.
Abner Mallity. All he knows about the board is the following:
-
The
increments in output voltage are exactly 2.5 mv.
-
The
lowest output voltage is a little less than -5 v.
-
The
highest output voltage is a little more than +5v.
Your job is to answer the following questions.
-
How
many bits are there in the D/A converter?
-
What
are the exact limits on output voltage (positive and negative)?
