Faasikorrektsed profiilfiltrid on nn joonfaasifiltrite eriliik, kuna igat joonfaasifiltrit saab muuta, lihtsalt selle kaalufunktsiooni nihutades, nullfaasifiltriks, mis on faasikorrektne filter.
Phase correct profile filters are a particular kind of the so called linear phase filters because any linear phase filter can be transformed (simply by shifting its weighting function) to a zero phase filter which is a phase correct filter.
