25<h2>Description</h2>
26
27<p>The <code>coefSelect</code> parameter specifies the active filter coefficients when <code>srcSelect</code> is set to <code>AX_PB_SRCSEL_POLYPHASE</code>. This parameter has no effect when other sample rate converters are used. Three sets of filter coefficients are provided, each with the frequency response indicated above. <BR><B>Note:</B> The slope for each filter is approximately -3dB/octave.</p>
28
29<p>The user must assert the <code>AX_SYNC_USER_SRCSELECT</code> synchronization flag in<code> axvpb.sync</code>, when setting a new <code>coefSelect</code> type.</p>
