Description	The design and application of a multi-channel, multiplexed quasi three-dimensional display are described. The device was developed, as part of the Bionics program, for simultaneous display of up to 30 channels of analog information. Based on an individual channel sampling rate of 100,000 samples-per-second and a minimum signal sampling rate of 10 samples-per-cycle, any input channel can contain frequency components from dc to 10,000 Hz. The all solid-state instrument makes extensive use of metal oxide semiconductor field-effect transistors (MOSFET) and integrated circuits. A novel signal sampling commutator was developed which samples signals at a 3.2 million samples-per-second rate. The basic multiplexer circuit utilizes a series of ultra-fast MOSFET switches and an integrated circuit summer. The time-division-multiplexed signal is amplified and processed to produce a quasi three-dimensional display effect. This effect is enhanced by techniques which produce intensity modulation of individual analog signals and which produce skew of the entire display. Switching transients are eliminated by turning-on the cathode-ray-tube only during transient-free times. All sweep, synchronization and intensity modulation signals are provided so that the device can be used with virtually any single-beam laboratory oscilloscope. The basic display can have wide application in the display of multiple channel information and can be readily adapted to specialized applications. (Author)
