Reconstruction Filter - an overview | ScienceDirect Topics

The filter's job is to remove the high frequency components, smoothing out the waveform. This is why the filter is sometimes referred to as a smoothing filter. This also serves to eliminate the aliases of the conversion process. The “standard” in the audio industry is to use a third-order Bessel function as the reconstruction filter.

Considering basic audio applications, the digital to analog conversion reconstruction filter (aka interpolation filter) is a low pass analog filter that removes all the image spectrum at the output before it goes to loudspeakers and retains only the baseband spectrum that resides in the filter's passband: inside its cutoff frequency of the ...

Reconstruction Filter Options • Digital and SC filter possible only in combination with oversampling (signal bandwidth B << f s /2) • Digital filter – Band limits the input signal àprevent aliasing – Could also provide high-frequency pre-emphasis to compensate in-band sinc amplitude droop associated with the inherent DAC ZOH function
