Design Analysis and Test of Fluidic Communication Components.

摘要

A fluidic communication system using turbulent two-dimensional flow as an operating medium was constructed. Input signals were amplified by means of amplitude modulation. Transmission lines of plastic tubing were used to transmit the modulated signal to the demodulation section. The inherent instability of a two-dimensional jet was used to provide a means of demodulation. Results reveal that modulation is successful if the input signal has a sound amplitude of at least 12% of the sound amplitude of the carrier frequency. The demodulator did not respond as predicted to the carrier frequency produced by the fluidic oscillators and thus did not demodulate the input frequencies with the degree of clarity as would be thought possible.
