A window amplitude discriminator which reproduces the waveforms of accepted action potentials

A device is described that consists of two parallel, three-level differential amplitude discriminators suitable for the selection of electrophysiological data. The present device has been designed for simplicity of construction and operation. The unit allows for a visualisation of the selected levels in precise relationship to the input signal oscilloscope channel. The design eliminates the possibility that a lower level will exceed a higher level. The resulting ease with which complex multi-unit electrophysiological data may be discriminated for analysis using the three digital reference level outputs, makes this instrument suitable for a wide range of electrophysiological experiments.
