Textbook Question
Chapter 40, Problem 1RQ
Explain the difference between digital inputs and analog inputs.
Expert Solution & Answer
To determine
The differences between the digital and analog inputs.
Explanation of Solution
The differences between the digital and analog inputs are as follows:
| Digital input. | Analog input. |
| Digital inputs are discrete time signals. | Analog inputs are continuous signals. |
| Digital inputs are represented as square waves. | Analog inputs are represented as sine waves. |
| Digital input consumes high bandwidth. | Analog input consumes less bandwidth. |
| Digital inputs are stored as binary bits. | Analog inputs are stored as wave forms. |
| High cost. | Low cost. |
