Document Summary
Closed book, closed notes, one 8. 5x11 inch hand-written formula sheet allowed. Work the problem in the space provided below each problem. The minimum gain for an inverting op-amp circuit is -1. The value for the resistor that goes between the + input and common for an inverting input op-amp circuit is found by the parallel combination of the input and feedback resistances. With normally distributed data, about 95% of the data will fall between the mean value and the mean value +2 . Bias errors can be detected and removed by statistical methods. High input impedance is desirable in measuring devices, since they will draw very little current from the measured system. Gain is the change in output per change in input (slope of output vs. input line). Range is the difference between the minimum and maximum inputs that produces a valid output. Precision is the difference between true and measured values.
