本装置可用于产生数字化信息音并将瞬时信息音频转换到适用于通讯的频谱位置上。为响应输入的数字数据,产生了分配频率和持续时间明确的不连续音频,并经济地组合为无假信号的单边带抑制载波信号。该信号的频率位置可方便地采用常用的混频方法确定。
The device can be used to generate digitized information tones and to convert the instantaneous information audio to spectral positions suitable for communication. In response to the incoming digital data, a discontinuous tone of defined distribution frequency and duration is generated and is economically combined into a single-sideband suppressed carrier signal without a glitch. The frequency position of the signal can be conveniently determined using a common mixing method.
