Hi Everyone I got a project but I dont understand and also where to start with.

DESIGN OF AN OP-AMP CIRCUITS


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.

It looks like a summer, and a gain stage, at a minimum.

All you need to do is to break that equation into formats that can be handled by a typical opamp block.

How can break the equation
