1. TYPICAL APPLICATION - SENSORS OF BRIDGE METHODS - SENSORS AND TRANSDUCERS 1.1 Write about the use of a strain gauges and measurement amplifiers for measuring pressure. (300 words). 1.2 Write about the use of filters in measurements and give examples of low-pass and high-pass filter designs. (300 words) 1.3 Simulate the gauge, the Wheatstone bridge, and the differential amplifier in Figure 1. Add to the system a second op-amp that is used to both amplify and apply a low-pass filter to the measurement signal. 1.4 Consider the strain gauge and the bridge equations. Use KCL to obtain each of the equations for each of the op-amps output, and the final output of the system considering both op-amps. You must plot and provide all the obtained graphics, schematic diagrams, system inputs and outputs of the system A 1 bao LP Random w w ww ww w Figure 1
