Abstract
Three methods of digital spectral analysis are compared, and their application to the investigation of current noise at very low frequencies is described. In each case periodic sampling of filtered noise voltages is followed by digital computation. Particular attention is given to the errors caused by aliasing in the determination of a power spectrum with the form characteristic of current noise.Keywords
