A frequency-domain derivation of shot-noise

Articles you may be interested in A random walk to stochastic diffusion through spreadsheet analysis Am. Unified derivation of Johnson and shot noise expressions Am. A shot-noise experiment with computer control and data acquisition Am. A formula for shot-noise is derived in the frequency-domain. The derivation is complete and reasonably rigorous while being appropriate for undergraduate students; it models a sequence of random pulses using Fourier sine and cosine series, and requires some basic statistical concepts. The text here may serve as a pedagogic introduction to the spectral analysis of random processes and may prove useful to introduce students to the logic behind stochastic problems. The concepts of noise power spectral density and equivalent noise bandwidth are introduced.
