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.
