Hereinafter, a detailed explanation will be given based on a -x embodiment of the present invention.

復調し、出力部にて記録ないしは表示出力する。When a data communication device uses, for example, a wired public telephone line, the data to be transmitted is modulated onto a carrier wave that matches the characteristics of the telephone line, that is, the frequency band. This frequency band is the audio band, for example approximately 300Hz to 3.0k.
Hz, etc. On the data receiving side, the received signal is demodulated and output for recording or display at the output section.

入力特性に適合する信号に変換される。Generally used for voice calls! ! , when performing data communication over a so-called telephone black wire, a data signal is input from the microphone input terminal of the radio in a suitable form, and is FM modulated using the output characteristics of the radio, that is, the frequency band. Sent. In this case, the data signal to be input to the input terminal is also a voice? 1? The signal is converted into a signal that conforms to the input characteristics of the radio, such as approximately 300 Hz to 3.0 kHz.

として通信装置を個別に構成するのは、不経済である。In such a relatively small communication device that uses a public telephone line and a telephone-side radio, it is advantageous to input and output data signals to and from the telephone line and the radio in a single-voice frequency band. Therefore, in such a device, it is uneconomical to separately configure communication devices for wired and wired communication devices.
