ABSTRACT:
Optimum tap coefficients corresponding to equalization characteristics are stored in a memory circuit and when an equalization characteristics is designated, an optimum tap coefficient is read out of the memory circuit and a transversal type equalizer is controlled by the read-out optimum tap coefficient. According to a modified embodiment, where a tap coefficient for a combined characteristic based on a combination of a plurality of transmission characteristics is necessary, a convolution operation of the tap coefficients for respective transmission characteristics is effected to determine a new tap coefficient which is used to set taps of the transversal type equalizer.
