The only required element in the sensor definition is the input element. In that
case, no degradation would be modeled, and the output would simply be the input.
understood to be +/-0.05 percent maximum variance. So, the actual value for the sensor
will be *anywhere* from 0.95 to 1.05 of the actual "perfect" value at any time -
even varying all the way from 0.95 to 1.05 in adjacent frames - whatever the delta
