Abstract
An input signal related to x- and y-axes is expressed by a complex variable (U), a transfer function of a low-pass or high-pass filter having a real-number coefficient is represented by F(s), a central angular frequency, which may be either positive or negative, to be passed or rejected, is represented by .omega., an imaginary number unit is represented by j, and a complex coefficient transfer function produced by replacing 's' in the transfer function F(s) with (s-j.omega.) is represented by F(s-j.omega.). An output signal related to the x- and y-axes which is generated when the input signal U passes through the complex coefficient transfer function F(s-j.omega.) is expressed using a complex variable (V), producing a transfer expression formula:
