    The response of electromechanical transducers can often be greatly improved by proper electrical termination that compensates for their coil impedance. The results of a detailed analysis are presented for two practical transistor amplifier configurations which produce negative output impedance. A push-pull power amplifier, based on this analysis, uses the bias stabilizing elements of the output st... View full abstract»

    A set of 80 filters is used to divide a random noise input spectrum of an audio system into 25 cps increments. An identical set operating as a spectrum analyzer provides a similar function on the system output. By means of an automatic regulating system using solid-state electronics, each of the 80 loops is closed independently, thus providing a unique control system compensating the audio system ...

    A new microphone, the Electro-Voice Model 642, is described. Designed particularly for television and motion picture applications where the usable microphone working distance must be a maximum, the model 642 has improved directivity and high sensitivity. The improved directivity is achieved by functioning as a first-order gradient microphone at bass frequencies and as a line microphone at higher f... View full abstract»

    Fourier series is generally considered to be one of the most basic mathematical tools of the communications engineers; when experimental support is sought for the theoretical conclusions obtained, it has the advantage of having readily available source equipment in the form of sine-wave generators. In many cases, however, due to the characteristics of the signals under study, the analysis into oth... View full abstract»

    Pole-zero concepts, with the associated techniques of signal flow graphs and root locus plots, are introduced and used in the analysis and synthesis of integrated loudspeaker-amplifier systems in the lower-frequency region. The case of the infinite baffle system is treated in detail, and formulas are developed for general voltage and current feedback. This is then simplified into a design method u...
