Overview
Checks if the input signal levels are within a specified upper and lower range.
Discussion
This module determines if the input signal falls within a specified range. The range is specified by the instance variables .lower and .upper. An input sample falls within the range if (in[i] >= .lower) && (in[i] <= .upper). The instance variable .withinRange is set to 1 if all of the input samples are within range. If one or more input samples are outside of the allowable range, then .withinRange is set to 0.
...
When the module is bypassed, the output is set to 1.
