Abstract
A receiver is provided, whereby bit error rate can be improved, while achieving savings in power consumption. The receiver comprises: a quadrature detector,for converting an intermediate frequency signal obtained on the basis of a reception signal to a base band signal; a comparator,for converting the base band signal to binary form after it has passed through a first LPF,, which is an analogue filter; a second LPF (CIC filter),for transmitting frequency components of the approximate square wave output by comparator,which are odd factors of the fundamental frequency of the signal; and a sampler,and comparator,which decode the output signal from the second LPF,in accordance with a clock reproduced by a clock reproducing circuit,on the basis of this output signal.
