Abstract:

During project PARKA, data were received, digitized and processed in real time by the UNIVAC 1230 computer aboard the prime receiving vessel SANDS. The final form of the processed data was displayed as listings and graphs with the values being expressed in db. To convert the data to db, two generalized programs, TENLOGTEN and CONLOGIT were written to calculate P 10 log10 X, where X is a fixed point number within a specified set of limits. The major differences between these two routines are the methods used to obtain the natural logarithm and the scaling necessary for the input values.
