A multiple temperature sensor system (120) includes a temperature sensor network (180) including temperature-sensing resistors RT1 and RT2 (186, 187) and frequency-selective filters (184, 185) coupled to the plurality of temperature-sensing resistors RT1 and RT2 (186, 187). The frequency-selective filters (184, 185) pass distinct time-varying signals into the temperature sensor network (180) and pass attenuated distinct time-varying signals out. The system (120) further includes a temperature measurement controller (161) coupled to the temperature sensor network (180) and configured to inject the distinct time-varying signals into the temperature sensor network (180), receive the attenuated distinct time-varying signals in response to the injection, with the attenuated distinct time-varying signals being attenuated by the temperature sensing resistors (186, 187), and generate two or more substantially simultaneous temperature values from the attenuated distinct time-varying signals. |
