As we have observed in previous parts of this course, in a digital system, signals can take on only two values: high or low. These values are often represented by two voltage levels. The most used ...

In the first installment of this course, we learned that a digital value is a quantity that varies “in steps” and can take on only a finite number of values. In today’s logic systems, only two ...

Common traits of digital multimeters (DMMs). Classifying DMMs by their amount of digits. What role do digitizers play in making voltage measurements? Measuring voltage may be the most basic ...
