摘要：An embodiment includes a method, comprising: receiving a modulated signal having modulation; generating a first signal in response to the modulation and a first sampling signal; generating a second signal in response to the modulation and a second sampling signal; and generating a distance in response to the first signal and the second signal. A ratio of a frequency of the first sampling signal to a frequency of the second sampling signal is a rational number.

主权项：1. A method, comprising: generating a modulated signal having a pulse train with pulses having varying amplitudes; receiving the modulated signal having modulation; generating a first signal in response to the modulation and a first sampling signal; generating a second signal in response to the modulation and a second sampling signal; and generating a distance in response to the first signal and the second signal; wherein a ratio of a frequency of the first sampling signal to a frequency of the second sampling signal is a rational number.
