Abstract : The patent relates to a fluidic device to demodulate a fluidic AC carrier signal to obtain a pure fluid signal. A modulated signal is impressed through an orifice to a cavity resonator. The output of the resonator is an orifice of smaller dimensions than the input orifice. Between limited frequency ranges the resonator will successfully demodulate AM and FM signals. If another orifice is placed in between the input and output orifices and opened to ambient pressure, the device will successfully demodulate FM and AM signals again within different but still limited frequency ranges.
