Hello,

So i am having some difficulties with OpAmps can anyone help me with this problem. A pic of the problem is attached below.

Thanks,

b) One half of the bottom part of the circuit: OpAmpl and/or OpAmp2: P1 M1 Xil R3 or 7 TR1 OA18LED1 PR1 OpAmpl is used as comparator. Which two values are being compared? · Why do you need potentiometer P1? »

Solution

# In comparator voltage of terminal 7 and 8 compared

# Potentiometer P1 can change the value of voltage at terminal 8 which can affect the comparator output
