Question

Project 3: Multisim Exercise Purpose The purpose of this exercise is to teach students to use Multisim to both plan circuits and Ve circuit design problems. In this exercise, you will design a circuit in Multisim that will be used in the Vibrating Beam II project bridge. One arm the bridge. This expands on an exercise that you amplified Wheatstone contains a strain gauge and a variable resistor sub-circuit used to balance This circuit is an performed in ECE 2161 Exercise Procedure (A)-Amplified Wheatstone Bridge Amplifier Using AD623 Instrument circuit that you will model is shown in Fis. 3. It is the same circuit that you wil construct of real components later (although you may choose gauge placement other than what is shown). You will need to choose and validate components that fit the constraints of the problem. Rigol Power Supply Strain Gauge Output AD623 Strain Gauge Balance Output Signal To LabView Ra Bridge Figure 3: Amplified Wheatstone Bridge The strain gauge that you will be using is the Vishay general purpose strain gauge with a nominal resistance of 120.0 To make this exercise more realistic, you will generate a variance in the resistor values that you use. Choose nominal 120 resistors for Rand Ra. Add variance to these resistors by making the value of each 12x and 12y where x is the last digit of your 800 number and y is the next to last digit. Select resistor values for the balance sub-circuit that will allow you to balance the bridge. [Hint; this sub-circuit
