Overview

LF2242 DEVICES INCORPORATED DEVICES INCORPORATED 12/16-bit Half-Band Interpolating/ Decimating Digital Filter 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 complexity of traditional analog anti-aliasing prefilters without compromising 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.
Likewise, by using the LF2242 as an interpolating pre-filter with a D/A converter, the corresponding analog reconstructio...
