Not specifically mentioned is that if you are doing something that involves a derivative (time-rate-of-change), having jitter in your sampling interval can result...
I don't see anything at the 12 Hz noted by kjh. As I read the frequency scale, the first "peak" is at 1.2 Hz. (The center of the plot is at 10^0 Hz, which is to...
The 500ns settling time of the ADC is what is required for full 12-bits of resolution to a full-range step input. (Resolution doesn't address things like ADC linearity...
You state that you want 40db of attenuation at half the sampling rate. That is one part in 100 of voltage. Yet you also state that you want 10-bits of resolution....
I do agree that a more complete description of the setup would be very helpful.But note that atorres stated in his initial posting that this was an _acoustic_ channel...

Very slight "nit-pick" on Tim Wescott's response where he says "surprised, if there's not also a frequency-dependent directional

You need to understand that dB is always the base-10 log of a _power_ ratio. dB = 10*log(P2/P1). This is commonly bastardized to be 20*log(V2/V1) which is correct...
