A relay capable of blocking a spurious output according to an embodiment of the present invention comprises: a digital signal processing unit which processes a digital signal for a received radio frequency (RF) signal; a digital terminal output unit which receives the digital signal which is processed by the digital signal processing unit, and is arranged at a terminal of digital signal transfer with respect to a signal transfer path; a power supply unit which supplies power for operating the digital signal processing unit and the digital terminal output unit; and a power delay unit which is arranged on a power supply path between the power supply unit and the digital signal processing unit such that, when the power supply by the power supply unit is disconnected, disconnection of the power supply to the digital signal processing unit is performed later than disconnection of the power supply to the digital terminal output unit. According to the present invention, it is possible to prevent a spurious output, which is generated by an abrupt power disconnection, from being outputted. |
