Abstract: A wireless ranging system generates, at a first device, a first plurality of counts, each of the first plurality of counts indicative of a transmit time of a corresponding packet, and further generates a second plurality of counts, each of the second plurality of counts indicative of a receive time of a corresponding packet.

Abstract: Exemplary aspects are directed to FM-radio receivers and methods to assess signals in a desired channel. In one example, a method includes demodulating a broadcast signal associated with a radio-frequency transmission using a desired-channel bandwidth setting and, in response, provide a first frequency-selective demodulated signal (e.g., MPX signal in an FM broadcast) and provide a magnitude indication, such as the raw signal level, of a second demodulated signal that is less frequency selective than the first frequency-selective demodulated signal. A level estimation circuit is used to assess a running representation (or effective average) of the magnitude indication over time. In this manner, a speed or rate at which the level estimator assesses the running representation is controlled based on a degree of deviation or offset as indicated by the first frequency-selective demodulated signal relative to a carrier frequency used for the broadcast signal.
