Abstract
The present invention relates to a method and a transmitter/receiver for transferring signals through a medium in pipes or hoses, whereby at a transmitter side pressure pulses are generated of various frequencies or in various frequency ranges, and for the purpose of providing a technology which eliminates error sources, it is proposed according to the invention that the pressure pulses be generated at the transmitter side as an organised and defined bit pattern in order thereby to achieve one or two-way alphanumeric communication.
