Q1: The voltage levels used to represent binary values (0 and 1) in a digital system are nearly equal in value.

ANS:B - False

In digital systems the logic 1 represents the high value of a signal which is greater than +5 volts and the logic 0 represents the low value which is nearly equal to +0.8 volts or less than it. So both the logics have different values with a very big difference.
