Abstract

본 발명은 무선 호출 수신기에 관한 것으로 특히 호출시에서 LCD화면을 주시하여 데이타를 확인함으로써 발생하는 불편함을 없애기 위해 음성 신호 및 MFC톤 신호를 발생하는 무선 호출 수신기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless call receiver, and more particularly, to a wireless call receiver for generating a voice signal and an MFC tone signal in order to eliminate the inconvenience caused by looking at the LCD screen and checking the data.

상기의 목적을 달성하기 위해 본 발명에서는 경보 발생부에서 종래의 톤 제어부 대신에 음성 신호 및 MFC톤 신호를 발생시키는 음성 신호 및MFC톤 신호 발생부를 설치하였고, 음성 신호의 처리를 위해 데이타 처리부를 경보 발생부내에 추가로 설치하였다.In order to achieve the above object, in the present invention, in the alarm generator, a voice signal and MFC tone signal generator for generating a voice signal and an MFC tone signal are installed in place of the conventional tone controller. It was installed further in the generating part.

호출 신호가 종래와 같은 방식으로 무선 호출기로 수신되어 증폭 및 변조되고 디코딩되어 경보 발생부로 정송되면, 본 발명의 일 실시예에 따른 경보 발생부에서는 디코더에서 전송된 신호를 경보 발생부 내에 장착된 데이타처리부에서 아날로그 신호로 변환이 용이하도록 처리하고, 음성 신호를 발생시키는 부분과 MFC톤을 발생시키는 두 부분으로 나뉘어 구성된 음성 신호 및 MFC톤 신호 발생부에서는 각각 원하는 신호를 발생시킨다. 상기 두 분에서 발생된 신호는 선택 스윗치의 입력으로 수윗치 제어부에서 하나의 신호만이 선택되는데, 이와같이 선택된 신호는 스피커로 출력된다. 따라서, 본 발명의 일 실시예에 따른 음성 신호 및 MFC톤 신호를 발생하는 무선 호출 수신기에서는 호출기가 호출되었을 때 LCD로 데이타가 출력됨과 동시에 음성 신호 또는 MFC톤신호가 출력된다.When the call signal is received, amplified, modulated and decoded by the wireless pager and transmitted to the alarm generator in a conventional manner, the alarm generator according to an embodiment of the present invention transmits a signal transmitted from a decoder to data mounted in the alarm generator. The processing unit processes the analog signal to facilitate conversion, and the voice signal and the MFC tone signal generator, which are divided into two parts for generating a voice signal and an MFC tone, generate a desired signal, respectively. Only one signal is selected by the level control unit as the input signal of the two switches, and the selected signal is output to the speaker. Therefore, in a wireless call receiver for generating a voice signal and an MFC tone signal according to an embodiment of the present invention, when a pager is called, data is output to the LCD and a voice signal or an MFC tone signal is output.
