    • Input data is modulated, a two-valued signal regarding a signal of a specific frequency is generated, and a logical arithmetic operation between the modulation data and the two-valued signal is executed. In accordance with the result of the logical arithmetic operation, the specific frequency component in the modulation data is detected. The modulating operation is controlled in accordance with the detection result. As mentioned above, the specific frequency component in the modulation data is detected by the logical arithmetic operation between the modulation data and the two-valued signal. By controlling the modulator on the basis of the detection result, the specific frequency component in the modulation data can be detected by a simple construction. For example, an amount of specific frequency component in the modulation data can be adjusted.
    • 输入数据被调制,产生关于特定频率的信号的二值信号,并且执行调制数据和二值信号之间的逻辑运算。 根据逻辑算术运算的结果,检测调制数据中的特定频率成分。 根据检测结果控制调制动作。 如上所述,通过调制数据和二值信号之间的逻辑算术运算来检测调制数据中的特定频率分量。 通过基于检测结果控制调制器,可以通过简单的结构来检测调制数据中的特定频率分量。 例如,可以调整调制数据中的特定频率分量的量。
