Abstract

PURPOSE:To make narrow the noise band of a transmission line inputted to an SCF (switched capacitor filter) of a reception side device, without losing the amplitude characteristics of an input signal, by transmitting the input signal through differentiation and outputting this transmission signal through integration. CONSTITUTION:The high band component of an input signal given to a transmission side input terminal 1 is emphasized at a differentiation circuit 13 and it is given to a band limit filter 2 and becomes a signal within the transmission band width to be applied to the transmission line. The signal added with noise at the transmission line enters an input terminal 4 of a reception side device and the high band of the signal is attenuated at an integral network 14 and the noise is attenuated from the lower end of the input signal. Thus, the input signal of the SCF6 has narrow noise band, and even if the clock frequency of the SCF6 is set lower by the value, the effect of a clock folding response on the SCF6 due to noise can be less.
