• (NEW) Triangular Averaging Distortions (PDF file)
   

Where do they come from ? Are they really a problem ? How to remove them ?
 

• Why does ALV prefer Multiple Tau Digital Correlation over linear or logarithmic correlation schemes ?
   

Advantages of Multiple Tau Correlation Schemes over Linear/Logarithmic Correlation schemes
 

• Why does ALV prefer 16/8 Multiple Tau over schemes with more “linear” channels per STC block ?
   

Do 32/16 or 64/32 channel Multiple Tau schemes really over advantages ?

• Multiple Tau ensures Optimum Baseline Accuracy !
   
• Linear Correlation at very fast sampling times - the ALV-LinCorr
   
• What is the gain in performing a dual cross correlation and averaging the two correlation functions ?
   

And, more important, are there dangers doing so ?
