Expert Solution & Answer
Chapter 5, Problem 25RQ
Explanation of Solution
Difference between analog and digital signals/devices:
Analog signals/devices | Digital signals/devices |
If the signal exists over the entire range of time period and if the signal value corresponding to its time is any numerical or fractional value, then it is known as analog signal. | If the signal exists over entire range of time period and if the signal value corresponding to its time is either high or low and no other values exists other than these two, then that signal is known as digital signal. |
The output of the analog device is analog signal... |
