PROBLEM TO BE SOLVED: To provide a digital transmission repeater capable of improving transmission efficiency, by reducing the band width required for transmission through a digital demodulation step and a digital modulation step, and to provide a signal transmission method which utilizes the repeater. SOLUTION: The digital transmission repeater converts a received analog signal into a digital signal, demodulates the converted digital signal into digital data, transmits the demodulated data, modulates the transmitted digital data into a digital signal, and converts the modulated digital signal into an analog signal.
