Decimal number 1 = binary number 001 = ABC Decimal number 7 = binary number 111= ABC, Decimal number 3 = binary number 011= ABC Decimal number 5 = binary number 101= ABC . Hence result.
All AND inputs must be 1 and inhibit 0 for output to be 1.
9. The fixed count that should be used so that the output register will represent the input for a 6 bit dual slope A/D converter uses a reference of -6v and a 1 MHz clock. It uses a fixed count of 40 (101000).
