General Directions: Read the questions carefully and answer (3*10=30marks)
1. Design a summing amplifier by choosing appropriate values of resistors an so that
the output is 5 times the sum of the input voltages. (you are free to use any number
of inputs, the type of op-amp, any value of resistors)
2. Derive the equation for the closed loop gain of the inverting and non-inverting
Amplifier using appropriate circuit diagrams.
3. Determine the values read by the measuring devices using appropriate formulae

Project Homework:
Create a simulation for a tank when the flowrate inside and outside the tank must
range between 0 and 10 lit/s:
1) The level should be controlled within a range between more than zero to 1000
lit.
2) An alarm must be launched when the level is out of range (less than 100 and
more than 900 lit).
3) When the capacity reaches to the maximum the motor turns OFF.
