摘要： A distance measuring device includes a calculating section that calculates, based on phase information acquired by a first device and a second device, at least one of which is movable, a distance between the first device and the second device. The first device includes a first transceiver that transmits three or more first carrier signals and receives three or more second carrier signals using an output of a first reference signal source. The second device includes a second transceiver that transmits the three or more second carrier signals and receives the three or more first carrier signals using an output of a second reference signal source. The calculating section calculates the distance based on a phase detection result obtained by reception of the first and second carrier signals and corrects the calculated distance based on information concerning an amplitude ratio of the first carrier signals received by the second transceiver.

摘要： A distance measuring device includes a calculating section configured to calculate, based on phase information acquired by a first device and a second device, at least one of which is movable, a distance between the first device and the second device. The first device includes a first reference signal source and a first transceiver configured to transmit two or more first carrier signals and receives two or more second carrier signals using an output of the first reference signal source. The second device includes a second reference signal source configured to operate independently from the first reference signal source and a second transceiver configured to transmit the second carrier signals and receives the first carrier signals using an output of the second reference signal source. The calculating section calculates the distance based on a phase detection result obtained by reception of the first and second carrier signals.

摘要： According to one embodiment, a transmitter includes a first buffer, a second buffer, a logic circuit, and a class E power amplifier. The first buffer receives a first sinusoidal signal, and converts the first sinusoidal signal to a first rectangular wave signal. The second buffer receives a second sinusoidal signal having a phase delay with respect to the first sinusoidal signal, and converts the second sinusoidal signal to a second rectangular wave signal. The logic circuit receives the first and second rectangular wave signals, and performs logical operation processing on the first and second rectangular wave signals to generate a logic signal with a predetermined duty cycle. The class E power amplifier receives the logic signal, and performs amplification operation based on the logic signal.
