Abstract
The present invention relates to a waveform equalizer and a method for controlling the same, as well as a receiving apparatus and a method for controlling the same whereby better receiving characteristics are provided than before. In a filter, registersthroughdelay an input DT; multipliersthroughmultiply outputs from the registers by filter coefficients Cthrough Crespectively; and addersthroughadd up outputs from the multipliers to acquire DT. A selectoreither outputs a timing signal at intervals of a symbol period of DTto drive the filteras a symbol rate equalizer, or outputs the timing signal at intervals of half the symbol period to operate the filteras a fractionally spaced equalizer. The present invention may be applied to waveform equalizers performing waveform equalization of the input signal.
