    "abstract": "An undergraduate level experiment is described to demonstrate the role of\nprobabilistic observations in physics. A capacitor and a DC voltmeter are used\nto randomly sample an AC voltage source. The resulting probability distribution\nis analyzed to extract information about the AC source. Different\ncharacteristic probability distributions arising from various AC waveforms are\ncalculated and experimentally measured. The reconstruction of the AC waveform\nis demonstrated from the measured probability distribution under certain\nrestricted circumstances. The results are also compared with a simulated data\nsample. We propose this as a pedagogical tool to teach probabilistic\nmeasurements and their manipulations.",
