General Description

The LF2242 is a linear-phase, halfband (low pass) interpolating/ decimating digital filter that, unlike intricate analog filters, requires no tuning.

The LF2242 can also significantly reduce the plexity of traditional analog anti-aliasing prefilters without promising the signal bandwidth or attenuation.

This can be achieved by using the LF2242 as a decimating post-filter with an A/D converter and by sampling the signal at twice the rate needed.
