Hello,
I would want to acquire an analog signal (314kHz bandwidth) filtered by an analog filter with 350kHz. This signal is injected in a 16 bits ADC (SAR ADC - 10MSPS max).
My application require low noise acquisition and I'm wondering what is the best way to minimize the noise from quantification and the noise limited in the band of interest ?
What is the interest of the oversampling technique (I know it's for minimize the order of the analog input filter), does it permit to minimize the white noise from the analog system or from the quantification effect ?
Do I need a digital filter after the overseampling ?
It's not very clear for me... I hope that you could help me
