Detailed Description

STK one-zero filter class.

This protected Filter subclass implements a one-zero digital filter. A method is provided for setting the zero position along the real axis of the z-plane while maintaining a constant filter gain.

by Perry R. Cook and Gary P. Scavone, 1995 - 2002.

Member Function Documentation

void OneZero::setZero ( MY_FLOAT theZero )

Set the zero position in the z-plane. This method sets the zero position along the real-axis of the z-plane and normalizes the coefficients for a maximum gain of one. A positive zero value produces a high-pass filter, while a negative zero value produces a low-pass filter. This method does not affect the filter gain value.

void OneZero::setGain ( MY_FLOAT theGain ) [virtual]

Set the filter gain. The gain is applied at the filter input and does not affect the coefficient values. The default gain value is 1.0. Reimplemented from Filter.
