WebNov 16, 2016 · The IF-filter in a communications receive chain is basically a low-pass filter or band-pass filter. It is used for rejecting the aliasing signals along with spurs generated by active components. The spurs include harmonics and IMD products, among others. With the filter, the receive chain can provide signals with higher SNR for the ADC to analyze. WebLow-pass filters exist in many different forms, including electronic circuits such as a hiss filter used in audio, anti-aliasing filters for conditioning signals prior to analog-to-digital conversion, digital filters for smoothing …
