Title: FM/DMB SIGNAL REPEATER AND RELAY METHOD CAPABLE OF OUTPUT TERMINAL CONTROL
Abstract:
The present invention relates to an FM/DMB signal repeater and relay method, wherein output terminal control can be performed in order to minimize, to within a tolerance range, an error occurring in a DC value from which an incoming signal is detected in a system where multichannel signals are introduced in an FM band or a DMB band. In order to transmit an FM signal and a DMB signal in a shaded area such as a basement or a tunnel, the present invention provides a signal repeater comprising: a first signal processing unit disposed at each floor; and a plurality of second signal processing units disposed at predetermined intervals, wherein a series of system processes are provided, in which the first signal processing unit separates an input FM/DMB signal, converts the separated signals into specified signals by using an amplifier, an attenuator, and a band-pass filter, generates the specified signals into one signal through a two-to-one synthesizer, and transmits the same to an external antenna and the second signal processing unit respectively through a divider, so as to receive both an FM signal and a DMB signal introduced through the external antenna, amplify and process the received signals, and transmit the same.
