Abstract
This document discusses, among other things, a GSM noise detection system configured to detect GSM noise at a pole of a four-pole audio jack using first and second comparators. The GSM noise detection system can include first and second comparators configured to compare a value of the pole to respective first and second thresholds and to provide an output indicative of the comparisons and a detection circuit configured to count changes in the output over a first period of time and to detect GSM noise at the pole of the four-pole audio jack using the count.
