    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.

    STANDARD VALUES FOR RESISTORS AND CAPACITORS
    (a) The standard E-12 values for fixed resistors are in the following ratios: 1 : 1.2 : 1.5 : 1.8 : 2.0 : 2.2 : 2.7 : 3.3 : 3.9 : 4.7 : 5.6 : 6.8 : 8.2.
    Examples: 100, 120, 150, 180, 220, 270, 330, 390, 470, 560, 680, 820Ω OR 1k, 1.2k, 1.5k, 1.8k, 2k, 2.2k, 2.7k, 3.3k, 3.9k, 4.7k, 5.6k, 6.8k, 8.2kΩ OR 10k, 12k, 15k, 18k, 22k, 27k, 33k, 39k, 47k, 56k, 68k, 82kΩ OR 100k, 120k, 150k, 180k, 220k, 270k, 330k, 390k, 470k, 560k, 680k, 820kΩ OR 1M, 1.2M, 1.5M, 1.8MΩ, etc.
    (b) The ratios for the standard values of the various types of capacitors are as follows:
    (i) pF range – 1: 1.2 : 1.5 : 1.8 : 2.2 : 2.7 : 3.3 : 3.9 : 4.7 : 5.6 : 6.8 : 8.2 Examples: 100pF, 120pF, 150pF, 180pF, 220pF, 270pF, 330pF, 390pF, 470pF, 560pF, 680pF, 820pF, etc. (
    ii) nF range – 1: 1.2 : 1.5 : 1.8 : 2.2 : 2.7 : 3.3 : 3.9 : 4.7 : 5.6 : 6.8 : 8.2 Examples: 10nF, 15nF, 33nF, 47nF, 68nF, 82nF, 100nF, 150nF, 220nF, 330nF, 470nF, 680nF, etc.
    (iii)µF range – 1: 1.2 : 1.5 : 1.8 : 2.2 : 2.7 : 3.3 : 3.9 : 4.7 : 5.6 : 6.8 : 8.2 Examples: 1µ, 2.2µ, 3.3µ, 4.7µ etc..

    It appears spec is correct, you already have a thread for this topic. Please do not start multiple threads on the same topic.
