Tutor description

1. Reference the textbook problem 5.4. Develop an ac bridge for Problem 5.3 Use 880 pF for all the bridge capacitors, and assume a 10-V rms, 10-kHz excitation. What is the maximum bridge offset voltage amplitude? 2. Reference the textbook problem 5.6. An LVDT with associated signal conditioning will be used to measure work-piece motion from –20 to +20 cm. The static transfer function is 2.5 mV/mm. The output will be interfaced to a computer via an ADC. a. What is the range of output voltage? b. If the desired resolution is 0.5 mm, how many bits must the ADC have? c. Design analog signal conditioning to provide interface to a bipolar ADC with a 5-V reference. 3. Reference the textbook problem 5.18. We will weigh objects by a strain gauge or R = 120Ω, GF= 2.02 mounted on copper column of 6-in. diameter. Find the change in resistance per pound placed on the column. Is this change an increase or decrease in resistance? 4. Reference the textbook problem 5.36. The bellows, diaphragm,
