Question
Please solve as much as you can, it would help me out alot. Thank you
Purpose of the lab: You need to design a Schmitt Trigger circuit to solve a noise issue you have in one of your circuits, because the noise is false-triggering a detector You determine that the signal you want goes below 2.5 V and above 5 V, so these need to be the set points for your Schmitt Trigger R1 D1 V1 U1 R4 VAC Rser 0 R3 R2 A. Design the resistance values 1. Design R1, R2 and R3 for approximate values of Vlow 2.5 V and Vhigh 5V. In addition, choose values such that the maximum supply current drawn from the supply is less than 1 mA. Review lecture notes if you are unsure how to do this. You can use MathCAD or Matlab, or any other calculation software. The kit resistors use standard values, so you must choose a value that is closest to what you calculate Calculated (or Chosen) Value Actual Resistor Value Used Resistance R1 Resistance R2 Resistance R3 2. Design R4 such that your LED is biased with 15 mA. Use the LM324's maximum output voltage you obtained in the last lab to calculate the value Calculated Value Actual Resistor Value Used Resistance R4Explanation / Answer
1)
Vupt = +Vsat (Rdiv1/[Rdiv1+Rdiv2])
=> 5V = 9V(Rdiv1/[Rdiv1+Rdiv2])
=> 0.555V = (Rdiv1/[Rdiv1+Rdiv2])
Vlpt = -Vsat (Rdiv1/[Rdiv1+Rdiv2])
=> 2.5V =9V (Rdiv1/[Rdiv1+Rdiv2])
=> 0.277V = (Rdiv1/[Rdiv1+Rdiv2])
