Similar to [[Programming Reference:ParallelCombination|&amp;lt;tt&amp;gt;ParallelCombination&amp;lt;/tt&amp;gt;]], the &amp;lt;tt&amp;gt;LinearCombination&amp;lt;/tt&amp;gt; class is a template that takes as arguments two filter class names.&lt;br /&gt;
The instantiated template is then a combined filter, and must be given its own class name by defining a struct that publicly inherits from the instantiated template:&lt;br /&gt;
&lt;br /&gt;
 #include &amp;quot;FilterCombination.h&amp;quot;&lt;br /&gt;

&lt;br /&gt;
The instantiated &amp;lt;tt&amp;gt;LinearCombination&amp;lt;/tt&amp;gt; template may then be referred to as a filter with name &amp;lt;tt&amp;gt;MyCombination&amp;lt;/tt&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
The resulting filter will apply existing filters &amp;lt;tt&amp;gt;Filter1&amp;lt;/tt&amp;gt; and &amp;lt;tt&amp;gt;Filter2&amp;lt;/tt&amp;gt; in sequence, such that the &amp;lt;tt&amp;gt;LinearCombination&amp;#039;s&amp;lt;/tt&amp;gt; input will be the input of &amp;lt;tt&amp;gt;Filter1&amp;lt;/tt&amp;gt;, and its output will we the output of &amp;lt;tt&amp;gt;Filter2&amp;lt;/tt&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;NOTE:&amp;#039;&amp;#039;&amp;#039; Due to existence of the [[Programming Reference:SubchainFilter|SubchainFilter]], the &amp;lt;tt&amp;gt;LinearCombination&amp;lt;/tt&amp;gt; class is largely obsolete.&lt;br /&gt;
