Algorithm Implementation Considerations - FIR Filter<br />
"FIR" means "Finite Impulse Response".<br />
They can easily be designed to be "linear phase" (and usually are).<br />
Put simply, linear-phase filters delay the input signal but don’t<br />
distort its phase.<br />
They are simple to implement. On most DSP microprocessors, the<br />
FIR calculation can be done by looping a single instruction.<br />
They are suited to multi-rate applications.<br />
FIR Filters are feedforward filters where the output values are a<br />
function <strong>of</strong> a finite number <strong>of</strong> past input values.<br />
FIR filters tend to be used where pass band characteristics are<br />
specified. These include the start and end <strong>of</strong> passband and ripple.<br />
