LMF380 Product details

Description

The LMF380 is a triple one-third octave filter set designed for use in audio audiological and acoustical test and measurement applications Built using advanced switched-capacitor techniques the LMF380 contains three filters each having a bandwidth equal to one-third of an octave in frequency By combining several LMF380s each covering a frequency range of one octave a filter set can be implemented that encompasses the entire audio frequency range while using only a small fraction of the number of
