Abstract: Decoder logic is limited to decoding of BCD digital signals to a seven segment code for numeric characters. Intermediate stages of decoding are utilized and complex MOS implemented gates reduce the logical circuitry for digital display of numeric characters by energizing segments of a seven segment display device.
