DESCRIPTION
The LF2242 is a linear-phase, half band (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 reconstruction post-filter circuitry can be simplified.
