This is the section that makes the book "hot" for scientists. Engineers care about throughput; scientists care about detecting a photon in a sea of thermal noise. Brophy dedicates serious real estate to Johnson noise (thermal), shot noise, and flicker noise. He teaches you how to calculate the SNR for a given circuit. This is gold for experimental physicists.
