Fir interpolator

WebAug 25, 2024 · Normally, without the use of polyphase implementations, we can interpolate a signal by simply inserting zeros, and then following that with a low pass filter to get rid of the higher frequency aliases that occur due to the zero insert. WebThe final plots shows the original signal (thin blue line), the filtered signal (shifted by the appropriate phase delay to align with the original signal; thin red line), and the "good" part of the filtered signal (heavy green line).

WebApr 10, 2024 · For interpolation, the signal needs to be filtered after the up-sampling, where it has to remove the spectral images. In decimation, the filter is applied before the down-sampling process to remove all components that would alias into the new passband. This makes interpolation and decimation two-stage processes.
