ABSTRACT:
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.
