Conservative Transient Analysis for Matlab post processing

To All,

I am doing Matlab post processing after getting an ADC waveform. If I use moderate accuracy I cannot reconstruct the waveform perfectly, it only happens with a conservative accuracy. Now my problem is, it has too many redundant points in the data, making Matlab post processing very difficult. Is there a way I can control the conservative accuracy? My input frequency is 3MHz and my sampling frequency is 100MHz. For every clock cycle I only need 1 value but I am getting almost 400 points for the same voltage. Any ideas on this?

Thank you,
Alfonso
