task is to do noise analysis of pico ammeter ADC output. here the input is 1pA DC signal. for which i have nearly 100000 output samples. sampling rate is 3.5Kps. these readings have error percentage nearly 0.178%. So i need to do its noise analysis like i have to detect which types of noises it contain? separation of those noises and actual signal and their plots. frequency ranges of the noises etc.i need to do this in matlab. i dont understand how to proceed.

Hi Sneha,
You didn't as a specific question so I can't answer specifically.
Apparently you have the measurement and you know the measurement value (1pA DC).
So to find the error, subtract the measurement from the known parameter you're measuring (1pA) and you have the noise.
To analyze the noise start with finding it's mean, then standard deviation, variance and ...
Good Luck!
