Inexpensive microprocessor controlled programmable function generators for use in electrochemistry

Several review articles on the use of microprocessors in the field of chemical instrumentation have been prepared by Dessy and co-workers (1-3). The major thrust toward their use in many laboratories would be expected to arise from their extremely high computing power provided at minimal cost. However, in reality, extremely limited use has been made to date by chemists working in small, low budget laboratories who could actually take direct advantage of the very low cost.
