<p>An infrasonic frequency resonant circuit and method of use thereof. An electric power distribution system (26, 24, 22, 18, 23) is employed both as antenna for ISF signals and as a source of inductive reactance for a resonant circuit tuned to a band within the ISF spectrum. A capacitor (42, 44) is placed from the neutral conductor (30) to the ground conductor (32) at an ac power outlet in a structure to form a resonant circuit ordinarily tuned to a band within the ISF spectrum. An ISF spectrum analyzer (54) is connected to the neutral and ground terminals of the resonant circuit to visualize ISF electromagnetic signals induced on the electric power distribution system in both the frequency domain and the time domain and so as to be more readily evaluated.</p> |
