difference signal การใช้

• That wider difference signals a drop in the relative price of TCI's debt.
• Stereo is generally achieved by sending the stereo difference signal, using a process called polar modulation.
• This was exploited in providing the non linearity necessary to produce good sum and difference signals.
• However, in SECAM the color difference signals, which are frequency modulated, need first to be decoded to e . g.
• The process of encoding the difference signal into the 23-53kHz band via double-sideband carrier-suppressed amplitude modulation is an instance of multiplexing.
• The UV representation of chrominance was chosen over straight R and B signals because U and V are color difference signals.
• In the SECAM system it contains the reference subcarrier for each consecutive color difference signal in order to set the zero-color reference.
• The ratio of these two beams normalises the difference signal and allows the direction of arrival of the signal to be calculated.
• Effectively, all horizontal stylus motion conveys the L + R sum signal, and vertical stylus motion carries the L " R difference signal.
• The color difference signals in SECAM are actually calculated in the YDbDr color space, which is a scaled version of the YUV color space.
• Consequently, if the colour difference signals use this unmodified version of'Y', the decoded colour display in the receiver will have saturation and hue errors.
• The X and Z color difference signals are further matrixed into three color difference signals, ( R-Y ), ( B-Y ), and ( G-Y ).
• The X and Z color difference signals are further matrixed into three color difference signals, ( R-Y ), ( B-Y ), and ( G-Y ).
• The frequency sum signal is filtered out and the frequency difference signal ( the IF ) is amplified and sent down the cable to the receiver:
• A simple 4-channel decoder could simply send the sum signal ( L + R ) to the center speaker, and the difference signal ( L-R ) to the surrounds.
• The monaural audio used for SuperTV's film broadcasts was transmitted on a subcarrier, which would later be used to transmit the difference signal of multichannel television sound after 1984.
• This " Dynaco patent " required a single resistor and a threeway potentiometer for the two rear speakers for generating sufficient phase difference signals for a feeling of ambience.
• Image processors operate in four steps : receive data from the CCD sensor, create the Y-color difference signal ( image processing ), perform JPEG compression, and save the image data.
• Two pairs of directional hydrophones were mounted on the torpedo nose, in the horizontal and vertical plane; the difference signals from the pairs were used to steer the torpedo left-right and up-down.
• That's similar to how broadcast television works ( PAL, NTSC, SECAM, etc )-where it is desirable to transmit a monochrome signal that's compatible with old-fashioned black-and-white TV's-and TWO color difference signals-the resulting three signals being called'YUV '.
