The use of the one chip calculator in the field of automatic computation of various functions is investigated in this thesis. As an example, the design of a digital Inductance and Capacitance meter is presented. An algorithm is developed to evaluate the Inductance or Capacitance of the particular component. The meter is implemented using the calculator chip to evaluate the required values. Among the series of Calculator Chips available the one used is T.M.S. 0117 NC Decimal Arithmetic Processor, made by Texas Instruments, Inc. It performs the required calculations and then presents the value in binary coded decimal form. These outputs can be interfaced with a seven segment display to present the value in visible decimal form. Some other applications are also suggested in which the one chip calculator could be used for automatic computation.
