    This paper describes a new video front-end processing system having improved resolution of digitizing. For this improvement two techniques are investigated, one is the summation of previous three A/D conversion results, and the other is 10° shift sampling. Next, an experimental system using a programmable logic device was developed and evaluated. As a result the noise level was decreased by 10... View full abstract»

    This paper describes a method of changing the time constant using gain control for playback equalizers and automatic level controller (ALC) of VHS VCRs using microprocessor-assisted processing. In the case of bipolar IC for a standard model, a total of 10 time constants which consist of external results of a VCR developed using this new method significantly reduced these time constants to 2. That ... View full abstract»

    This paper presents a new digital FM demodulator using a discriminator with a cosine-shaped S curve. In the present arc-tangent type demodulator, three functional operations are required to calculate the instantaneous frequency. Since the gate count for such functional operations is large, it is necessary for this to be reduced in order to promote system on a chip. Therefore, a cosine type demodul... View full abstract»

  • A power line FSK transceiver with reduced power consumption

    Publication Year: 2001, Page(s):207 - 213
    Cited by:  Papers (6)

    A versatile low-power half-duplex FSK transceiver for power line communication network applications is presented. The proposed power-line modem (PLM) satisfies the requirement of several protocols for power-line communications. The device operation is fully controlled and programmed through an internal 24 bit register. It operates from a single 9 V supply (5 V is possible if no power delivery is r... View full abstract»

    In this paper, we describe the design, implementation and testing of the IMT-2000 (International Mobile Telecommunication-2000) system test plant for W-CDMA (wideband-code division multiple access) base station modulator and demodulator based on cdma2000 RTT (Radio Transmission Technology). The performance of the implemented base station is measured and compared with theoretical performance bound.... View full abstract»

  • Boost bridge audio amplifier

    The main difference in topology of a boost bridge amplifier and state-of-the-art class-D amplifier is in the connection of a loudspeaker between a power supply and a switching bridge. The boost bridge amplifier provides four times higher peak power at the loudspeaker than the power, which can be achieved by a class-D amplifier from the same power supply. Total harmonic distortion and amplifier eff... View full abstract»

    Traditional error concealment systems for still images compressed in the discrete cosine transform (DCT) domain and transmitted over lossy channels are not suitable for JPEG2000 compressed images. In this paper a novel error concealment scheme for images compressed in wavelet domain is proposed. It is based on data hiding techniques to reconstruct missing data of the region-of-interest (ROI). The ... View full abstract»

    This paper presents a fast algorithm for de-interlacing of video images using a shortest path technique. The algorithm applies dynamic programming techniques to find a shortest path in a cost matrix. The motion information obtained from this shortest path is used to re-align the fields of a video image. By using the shortest path via dynamic programming, the motion information estimated is more re... View full abstract»

    An image interpolator with image improvement is proposed and implemented for a FPD (flat panel display) in this paper. We propose an adaptive pseudomedian filter for the interpolation of images and a real-time contrast controller for image improvement. The proposed interpolation algorithm is based on a pseudomedian filter and uses transposed sub-windows according to the correlation of pixels in th... View full abstract»
