The smooth predictable envelope and quasi-periodicity of impulse response allows for potential ways to design ultralow-complexity FIR filters. By introducing an extrapolated impulse response technique, a first attempt successfully reduced the arithmetic complexity of FIR filter from oðNÞ to oð ffiffiffiffiffiffiffi 2N p Þ comparing with direct form.
