You have a strain gauge with a nominal resistance of 10K and varies by only +/- 1% under maximum load. Design a circuit to measure this sensor with a output range of a full 0-5V. Part 2: If you needed 1000 different levels of digital accuracy, how many bits would you need in an ADC?
Draw a block diagram of the previous product I worked on and explain how it worked.
No difficult quest were asked
Transistor circuit for a NAND gate.
Assume that a new sensor being developed and you have to come up with ideas to test it.
You have a metal sphere hanging from a spring in an elevator. You would like to measure the movement of the ball relative to the carriage throughout the day. A.) Come up with a list of devices you could use to measure the movement. B.) Use the capacitance formed by the ball and a metal plate on the elevator floor to create a measurement device for a microcontroller.
