Abstract
A repeater for use in a digital wireless teletype-capable telephone receiver. The repeater includes a receiver for receiving an input signal and interpreting the input signal to identify Baudot characters represented by the input signal, and produce a receiver signal comprising identifications of the Baudot characters represented by the input signal. The repeater also comprises a transmitter which produces an output signal based on the receiver signal produced by the receiver. The transmitter generates the Baudot codes identified to it by the receiver. The repeater therefore removes distortion which may be present in the input signal.
