In <a href="http://www.microtelecom.it/perseus/" target="_blank">http://www.microtelecom.it/perseus</a> the following is mentioned:<br>> Without preselection
filters, harmonic distortion in direct sampling receivers is the source of high spurious signals since even the best wideband
amplifiers can't provide the required 110/115 dB HD suppression.<br><br>Would it be possible to correct in software for the non-linearities of the amplifier and ADC to improve the receiver performance in terms of spurious free dynamic range and harmonic distortion ?
<br>Will the receiver improve if the ADC samples are looked-up in a table that passes the linearized version of the signal?<br><br>73,<br>Guido<br>PE1NNZ<br><br>
