    1. The problem statement, all variables and given/known data

    Consider an ideal voltage generator. If an ideal voltmeter is connected to the generator calculate the value of A (coefficient in v(t))

    given:

    v(t)=|A+BAcos(377t)|

    V given

    what kind of voltmeter? DC? AC? Phase-angle?

    Hmmm it isn't specified but I'm guessing the voltmeter is AC.

    If it's AC, is it calibrated for sinusoidal inputs, or rms AC, or ??

    This question needs an answer in order to proceed.

    I believe it is calibrated for sinusoidal inputs.

    So assume a meter that reads only + voltages (it reads negative voltages as zero), then passes the voltage thru a low-pass filter of appropriate gain, and then into a dc voltmeter.
