Abstract (in Japanese) (See Japanese page) 
(in English) A field of the digital signal processing demand digital filters with changing frequency characteristics.
The filter that can change the frequency characteristic is instantaneously called a variable filter.
In this paper, we present a reduction method of polynomial coefficients for variable digital FIR filters with plural parameters.
In this method, we use the Taylor theorem enhanced to the multivariable.
The polynomial coefficients have been reduced by disregarding high order coefficients.
