SUMMARY
The discussion centers on the behavior of 1/f noise at zero frequency (DC) and its implications. It is established that 1/f noise is inversely proportional to frequency, but at zero frequency, the power spectrum does not approach infinity due to practical limitations such as finite observation time and system size. These factors introduce a cutoff beyond which the 1/f power spectrum is no longer applicable, clarifying why infinite voltage is not observed in DC measurements.
