Abstract
SPECULATIONS are often made about the possible extent of the 1/f noise spectrum which is exhibited by many electronic devices at low frequencies. This has been found to extend to the lowest frequencies so far investigated (about 10−4 Hz), but the view is often expressed that it can only hold for a limited frequency range. The reason invoked is that the total noise power would tend to become infinite if the 1/f spectrum extended over a sufficient frequency range. This is either implied or explicitly stated in several papers1–6, and I examine the question in this communication.
