Abstract: Provided is an encoding apparatus for integrally encoding and decoding a speech signal and a audio signal, and may include: an input signal analyzer to analyze a characteristic of an input signal; a stereo encoder to down mix the input signal to a mono signal when the input signal is a stereo signal, and to extract stereo sound image information; a frequency band expander to expand a frequency band of the input signal; a sampling rate converter to convert a sampling rate; a speech signal encoder to encode the input signal using a speech encoding module when the input signal is a speech characteristics signal; a audio signal encoder to encode the input signal using a audio encoding module when the input signal is a audio characteristic signal; and a bitstream generator to generate a bitstream.

Abstract: A radio frequency (RF) test device such as a spectrum analyzer may include an RF attenuator to attenuate a received RF signal; a mixer to down-convert the attenuated RF signal; an IF attenuator to attenuate the down-converted signal; an analog-to-digital converter (ADC) to digitize the attenuated, down-converted signal; and a processor, which may select attenuation values for one or more of the RF attenuator and the IF attenuator based on an error magnitude vector (EVM) analysis, an RF signal type, and/or a signal level at an input of the ADC. The processor may use a look-up table for the selection. Initial attenuation values may be selected based on an expected RF signal type, RF signal frequency, and/or RF signal bandwidth. The attenuation values may also be selected in an iterative manner stepping the attenuation values up or down.

Abstract: Disclosed is an LPC residual signal encoding/decoding apparatus of an MDCT based unified voice and audio encoding device. The LPC residual signal encoding apparatus analyzes a property of an input signal, selects an encoding method of an LPC filtered signal, and encode the LPC residual signal based on one of a real filterbank, a complex filterbank, and an algebraic code excited linear prediction (ACELP).

Abstract: A semiconductor device includes a first interlayer insulating film disposed on a substrate and having a first trench. A first lower conductive pattern fills the first trench and includes first and second valley areas that are spaced apart from each other in a first direction parallel to an upper surface of the substrate. The first and second valley areas are recessed toward the substrate. A second interlayer insulating film is disposed on the first interlayer insulating film and includes a second trench that exposes at least a portion of the first lower conductive pattern. An upper conductive pattern fills the second trench and includes an upper barrier film and an upper filling film disposed on the upper barrier film. The upper conductive pattern at least partially fills the first valley area.

Abstract: A display device includes a display panel including a main area and a sensor area. Sensor devices overlap the sensor area of the display panel in a thickness direction of the display panel. The display panel includes first subpixels, which are disposed in the sensor area, and second subpixels, which are disposed in the main area. The number of transistors of each of the first subpixels is different from the number of transistors of each of the second subpixels.
