Conversion circuit handles binary or BCD

摘要

Systems requiring arithmetic operations on data usually perform those operations in binary form. As a result, they must convert the data to BCD form for display purposes. Address-selection information from digit switches, on the other hand, must be converted to binary form for use in memory-addressing operations. " For applications not requiring fast conversion, a single circuit that can perform both conversions proves adequate. One such circuit (Figure 1) utilizes up/down counters to obtain the desired results.
