PURPOSE:To obtain a bias controller suitable for Adaptive Interference Suppression Filter(AISF) by outputting a channel control signal based on channel ID signals rearranged by a sorting section. CONSTITUTION:The bias controller of the AISF is provided with a channel data and channel ID latching section 31, a sorting section 32, an AISF control signal generating section 33, and a timing clock generating section 34. Then a bias shifting signal corresponding to the spectral intensity of each channel with a different center frequency outputted from the AISF is acquired as a digital data, the quantity of data is compared, channel ID signals representing the channel number in the order of the spectrum intensity to generate a AISF control signal. Thus, the bias control circuit suitable for the AISF is obtained. |
