  • More on nonlinear distortion correction

    Further consideration is given to basic amplitude limitations which may apply to the complementary distortion method of nonlinear distortion correction. It is found, in disagreement with others, that points at which the differential gain is zero or infinite do not limit the amplitude over which complete correction is possible but that relative maxima, minima, gain zeros, and infinite-gain points i...

  • A simplified noise theory and its application to the design of low-noise amplifiers

    Any noisy amplifier can be represented by an equivalent noiseless amplifier plus two noise generators either at the input or the output of the amplifier. The choice of two particular noise generators (the equivalent short-circuit noise voltage and the open-circuit noise current) to characterize a noisy amplifier has a number of advantages over the concept of noise figure. The noise generators can ... View full abstract»

  • Average vs RMS meters for measuring noise

    It appears that the controversy is still alive over whether average reading or root-mean-square reading meters should be specified as standard for the measurement of noise. This being the case, it is worthwhile to consider the entire subject from the standpoint of basic fundamentals, to determine what are the significant quantities involved, and then proceed to investigate which type of meter yiel...

  • An adjustable shelf-type equalizer with separate control of frequency and limiting attenuation or amplification

    This device provides for control of the high-frequency content of an audio program, allowing the operator to choose independently: 1) the frequency above which equalization is to occur, and 2) the maximum correction in signal strength which results in the range of frequencies under correction. Three operating controls are used. One control determines whether the high-frequency signals shall be inc... View full abstract»

  • "Apparent bass" and nonlinear distortion

    Publication Year: 1961, Page(s):117 - 121
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (503 KB)

    A discrepancy between the "apparent bass" response heard by the average music listener and anechoic-chamber measurements has been noted for some small loudspeaker systems. This may be caused by the psychoacoustic response to the generation of harmonic distortion by the nonlinear suspension and the inhomogeneous flux gap density in a small speaker. An electrical analog, with controllable distortion... View full abstract»

  • The concept of linear interpolation in spectral compensation

    Publication Year: 1961, Page(s):122 - 131
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1574 KB)

    Spectral compensation is usually achieved with equalizers cascaded so as to generate a desired response. In the concept of linear interpolation, a series of points are located along the desired response and linear interpolation provided between adjacent points. This is accomplished with contiguous band-pass filters arranged so as to minimize the effect of filter crossover. The performance limitati... View full abstract»
