    In making signal to noise ratio measurements for monophonic and stereophonic FM signals, the types of noise weighting circuit and deemphasis circuit used have significant effects on the results. In this paper the relative values of noise power are calculated and presented for several common deemphasis and weighting circuits and various types of noise spectra. With these results it is possible to meaningfully compare results obtained from different measurements and to predict how results will scale from one measurement to another. View full abstract»

    A research program to study factors of human interaction with videotext/teletext technology, hereafter referred to as videotex, should consist of three fundamental components. First, formative and technological research are used in the conceptualization and design stages of system hardware and software development. View full abstract»

    A video codec system for carrying one broadcast quality NTSC color TV channel at a rate of 42.935 Mbits/s has been proposed. The receiver of the video codec system is developed for recovery of the original signal. The receiver accepts a 42.935 Mbits/s serial TDM data stream with a synchronous clock from the Transmitter. The receiver detects the unique sync code and inserts a horizontal blanking pattern which has been removed from the transmitting data. The audio and video data are separated at the outputs of the demultiplexer. The 4/8 bit dual length code word of the video data is smoothed out by a buffer memory and fed to the DPCM reconstruction loop. The analog NTSC color video signal as well as the audio signal are reconstructed after the D/A conversion. This paper describes the design and development of the receiver portion (Fig. 1) of the codec which is capable of transmitting'one color signal at broadcast standards on a T3 digital link.

  • Bandpass Asymmetry and Envelope Distortion

    The nonlinear bandpass response of an analytic signal is evaluated and is defined by scaling polynomials as even powers of the real envelope. Bandpass asymmetry is shown to reduce the spectral complexity in the nonlinear transformation, suggesting merits in nonsymmetrical bandpass amplification. View full abstract»

    A micro-computer based apparatus has been developed for the measurement of television picture quality when debased by noise. The basic principle is the simulation of the human eye by optical, electronic and software means. The micro-computer measures the standard deviation of light intensity caused bynoise. This standard deviation is transformed to give a quality rating. The measurements of quality done with the apparatus agree with the results of subjective tests which have been performed. The main advantage of such an apparatus is that it can measure the picture's quality in a few seconds instead of the many days required for subjective tests. View full abstract»
