A filter is a frequency selective circuit that allows a certain frequency to pass while attenuating the others Filter could be analog or digital Analog filters use
We focus on linear-phase FIR filters, because if linear phase is not needed, then IIR is probably preferable anyway We focus on lowpass filters, since
