For testing 10bits ADC in simulation level, I extract data from Hspice and import the data into Matlab to do FFT. Suppose my input is 2.11MHz and sampling rate is 10MHz, I use matlab codes to DAC in order to get the ideal analog output and then test SNR, ENOB, THD.

The problem is should I add a low pass filter before doing FFT?

Thx in advances.
