MULTIPLE STAGE CONSIDERATIONS Since multiple noise generators non-coherent, their total effect root-of-the-sum-of-the-squares various noise generators given amplifier input. This makes orders-of-magnitude lower noise sources less important than higher magnitude source. Therefore, when considering combined signal-to-noise multiple stages gain, first stage chain dominates making design parameters most critical. this reason good practice make preamp stage gain high practical boost signal levels second stage allowing least order-of-magnitude above second-stage noise. instance, signal input which exceeds input noise following stage factor 10:1 will only degraded 0.5% neglecting first-stage noise. preceding example with first-stage output signal mVRMS S/N, output noise 0.16 Following this with band limited gain-of-10 second-stage, with noise source noninverting input, combined calculated follows: (assume source resistance from amplifier Second stage output noise
