Abstract: An optical device is disclosed. An optical device of the present invention that generates a depth map for an object comprises: a projector for irradiating electromagnetic waves onto an object; an optical receiver for receiving reflected waves reflected from the object; and a processor for generating a first depth map for the object on the basis of the direction of arrival of the received reflected waves, generating a second depth map for the object on the basis of the arrival time of the received reflected waves, and combining the first depth map and the second depth map and generating a depth map for the object.

Abstract: An electronic device and a controlling method of the electronic device are disclosed. The electronic device may include: a memory configured to store at least one instruction, and at least one processor, comprising processing circuitry, configured to execute the at least one instruction, and at least one processor, individually and/or collectively, is configured to: obtain an audio signal, input the audio signal into a preprocessing module and obtain feature information indicating features included in the audio signal, input the feature information into a vector obtaining module and obtain a feature vector corresponding to the audio signal based on the obtained feature information, and input the feature vector into a classification module and identify whether the audio signal is compressed two or more times. Here, each of the modules may include a neural network, and the feature information includes information on at least one from among a feature on a frequency domain of the audio signal, a feature on a time domain of the audio signal, and a feature on a frequency-time domain of the audio signal.

Abstract: The present invention relates to an apparatus for obtaining a signal, which may comprise an electronic apparatus comprising: an antenna for receiving a signal via at least one channel from an external apparatus; a reference signal generation unit for generating a reference signal on the basis of frequency-related values and transmitting the reference signal to a signal correlation unit; a signal correlation unit for calculating a correlation value between the signal and the reference signal; a correlation maximum signal identifying unit for identifying a time value corresponding to a correlation value exceeding a preset reference value from among correlation values calculated from the signal correlation unit and delivering the identified time value to a least square calculation unit; and a least square calculation unit for calculating at least any one of a magnitude value and a phase value of a frequency on the basis of the identified time value and delivering the calculated value to the reference signal generation unit. However, the present invention is not limited to the above-described embodiment, but may include other embodiments.
