A simple circuit for producing vertical arrays of analogue signals and dot raster displays of nerve and muscle action potentials.
It is often helpful to display analogue signals such as electromyograms, electroencephalograms, nerve action potentials, etc., in a regular vertical array. A special case of this display is the widely-used dot raster. This paper describes a simple circuit which enables up to 31 analogue signals to be thus displayed on an analogue storage oscilloscope screen or X-Y plotter. A modification permits up to 255 trials to be displayed. The same circuit produces a standard, dot raster display from standard pulses representing nerve or muscle cell action potentials.
