Transmission of digital pneumatic signals along a wire communication line

The paper is concerned with new ways of accelerated transmission for digital pneumatic signals. These are transmitted along a wire by using piezoceramic elements without an electric supply source. The receiving and transmitting units rely on piezoceramic elements. Equivalent circuits of these units are designed and their operation described with various ways to transmit pneumatic signals. The specifics of data processing and noise parameters are described and noise immunity of transmitters is estimated.
