如题，现在做的一款信号采集芯片，想问下怎么测试噪声?
Professional measurement is to use Spectrum Analyzer
but the minimum measured frequency need low enough to 1Hz and thus can see the flicker noise
The HP3562A Spectrum Analyzer is a best choose.
See Kofi , Rong Wu Paper....
Thanks for your help, 1mHz is 1 micro Hz, is right? And how to caculator integrator noise?
