| Language: | English (en) |
| Summary: | Infinite impulse response (IIR) filters are an alternative to finite impulse response (FIR) filters. Often, an IIR implementaion can meet a given filter specification with less computation than an FIR implementation, but IIR filters induce nonlinear phase and are more sensitive to numerical problems. |
