I HAVE A PROJECT BUT NO IDEAS START FROM WHERE, BELOW IS THE QUESTION

Given that the pressure sensor produces an output voltage (Vs : sensor output voltage) according to the equation Vs = (P x 0.131 )+ 1.683. This equation can be expressed in terms of pressure (P) versus sensor voltage (Vs). ie.

P = (Vs - 1.683)/0.131

You are to design the amplifier circuit for this sensor using any combination of inverting amplifiers, non-inverting amplifiers, summing amplifiers together with a 1V reference voltage source. The two input signals of this circuit are sensor voltage (Vs ) and an 1V reference source (Vref ) and the circuit should produce an output voltage (Vo) indicating the pressure (psi) according to the equation Vo = P (psi)

i.e When P = 0 psi , Vo = 0V and

P = 10 psi, Vo = 10V.

P = -10 psi, Vo = -10V.
