本文介绍用微处理机处理莫尔斯电报信号的发送装置。本装置能有效地处理来自键盘的各种英文字母、数字和符号,由专门设计的、可用少量中小规模集成电路构成的发送控制电路,实现莫尔斯电报信号的发送。采用本装置,在软、硬件的配舍下,能成功地实现40码/分—250码/分速率的电报信号发送,实时控制准确,音响性能良好,完全可以与人工手键发报兼容。
This article describes a microprocessor that processes morse telegrams. The device can effectively deal with all kinds of English letters, numbers and symbols from the keyboard, and can be sent by a specially designed transmission control circuit which can be composed of a small number of small-scale integrated circuits to realize the Morse telegram. With this device, under the allocation of software and hardware, the telegraphy signal of 40 yards / min -250 yards / min can be successfully transmitted, with accurate real-time control and good sound performance, which can be completely compatible with the manual key transmitter.
