    Abstract: An apparatus and method for ultra wideband (UWB) communication, using a dual band pass filter (BPF) is disclosed. The UWB communication apparatus may include a first BPF performing a first band pass filtering with respect to a UWB signal, a second BPF that has a center frequency differing from a center frequency of the first BPF, and performs a second band pass filtering with respect to the UWB signal, a first envelope detector that detects a size of a first signal filtered in the first BPF, a second envelope detector that detects a size of a second signal filtered in the second BPF, and a demodulator that demodulates a UWB signal, using the size of the first signal and the size of the second signal.

    Abstract: The present disclosure provides an X-ray imaging apparatus and control method thereof, for guiding the user to intuitively recognize an actual dose of X-rays and select a proper dose, ultimately a condition for low dose of X-ray irradiation by providing the user with information about an actual X-ray dose to which an X-ray filter effect is reflected. In accordance with an aspect of the disclosure, an X-ray imaging apparatus includes: an X-ray source configured to generate and irradiate X-rays according to an X-ray irradiation condition including at least one of a tube voltage, a tube current, or a filter; a display configured to provide a graphic user interface to receive a choice about the X-ray irradiation condition; and a controller configured to obtain a parameter that represents a dose of radiation, to which an influence of the filter is reflected, based on the selected X-ray irradiation condition and control the display to display the parameter.
