    Stereophonic playback systems are studied to determine the accuracy with which they can reproduce the geometry of the original sound. Sounds were generated in a geometric pattern, recorded, and reproduced over a loudspeaker array. The methods used were similar to those used by Steinberg and Snow in 1933. Using two sound tracks, a derived center playback channel, and corner placement of flanking sp... View full abstract»

    An analytical as well as experimental evaluation of the electromechanical equivalent circuit constants of a two-channel flexural-type element is presented. This unit is a hollow cylindrical PZT ceramic structure electroded and polarized to be responsive to two signals perpendicular to each other. The electromechanical equivalent circuit chosen to represent this element is based on the analogy betw... View full abstract»

    The development and performance capabilities of a dual pentode using a single cathode, two separate Framelok grids and a twin-plate structure contained in one envelope is described. This new pentode, known as Type 6DY7, is a high-performance tube with superior characteristics of uniformity and stability obtained from its unique structure. Such factors as greater uniformity in tube-to-tube characte... View full abstract»
