Oscilloscope error

  1. Jul 4, 2015 #1
    1. The problem statement, all variables and given/known data
    "An instrument (oscilloscope) is prepared to measure a sinusoidal periodic wave, compute the measurement error if the same instrument is used to measure the wave indicated in figure 1

    (The wave is much more like a sawtooth wave, sorry for bad drawing)


    2. Relevant equations
    ((Measured-True)/(Measured)) × 100

    3. The attempt at a solution

    Actually, I don't how to start, should I assume that sinusoidal wave is 4V peak (from 6V to 10V above, and 6V to 2V below) and substracting the values?

    The key to this probably lies in the meaning of an instrument "being prepared" for measuring a sinusoid. Have you encountered this phrase in any earlier exercises, or in the laboratory?

    Are you sure the question says it's an oscilloscope that is the instrument that is being prepared, or is that your interpretation?
