摘要： A stylus is configured to use a local wireless receiver to assess interference at a transmission frequency that corresponds to the stylus's location-information wireless transmitter. By one approach, the stylus carries out this assessment during transmission nulls for the location-information wireless transmitter. If desired, the wireless receiver can operably couple to (and hence share) a same antenna that operably couples to the location-information wireless transmitter. By one approach, the stylus is configured to change the transmission frequency of the location-information wireless transmitter as a function of determining that the aforementioned assessed transmission frequency is experiencing more than a predetermined level of interference.
