|
||||
STK one-zero filter class.
|
||||
<p>
|
||||
This protected <a class="el" href="classFilter.html">Filter</a> 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.

Set the zero position in the z-plane.
|

<p>
|
||||
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 <em>gain</em> value. </td>

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.
