Abstract

PURPOSE:To secure only a kind of the variable coefficient which is not required to be memorized in ROM by ensuring the same selection for the multiplication coefficient of the multiplier which decides each variable characteristics. CONSTITUTION:The input signal is supplied to delay units 11-14 which are connected in series, and the signals drawn out from each step of the delay unit to be combined and added after receiving the weighting. One of these addition signals is supplied the series connection of the multiplier to decide the basis property of the filter and the multiplier to decide the varying property respectively. And the output signal is added with another addition signal to be supplied to the series connection of the multiplier to decide the basic property of the filter and the multiplier to decide the varying property. Then the output is added to another addition signal. This action is repeated hereafter in sequence. The final addition output is made to pass through the multiplier which decides the basic property of the filter and then turned to the output, and the multiplication coefficient is selected to the same one for multiplier 21 and 25 which decide each varying property. Thus, only one kind of the variable coefficient exists to eliminate the necessity for memorization into ROM.
