  2. Octal - Wikipedia

    en.wikipedia.org/wiki/Octal

    To convert integer decimals to octal, divide the original number by the largest possible power of 8 and divide the remainders by successively smaller powers of 8 until the power is 1. The octal representation is formed by the quotients, written in the order generated by the algorithm. For example, to convert 125 10 to octal: 125 = 8 2 × 1 + 61

  4. Quaternary numeral system - Wikipedia

    en.wikipedia.org/wiki/Quaternary_numeral_system

    As with the octal and hexadecimal numeral systems, quaternary has a special relation to the binary numeral system.Each radix four, eight, and sixteen is a power of two, so the conversion to and from binary is implemented by matching each digit with two, three, or four binary digits, or bits.

  6. Split octal - Wikipedia

    en.wikipedia.org/wiki/Split_octal

    Syllabic octal is an 8-bit octal number representation that was used by English Electric in conjunction with their KDF9 machine in the mid-1960s.. Although the word 'byte' had been coined by the designers of the IBM 7030 Stretch for a group of eight bits, it was not yet well known, and English Electric used the word 'syllable' for what is now called a byte.

  7. Transponder (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Transponder_(aeronautics)

    Four octal digits can represent up to 4096 different codes, which is why such transponders are sometimes described as "4096 code transponders." [ 10 ] The use of the word "squawk" comes from the system's origin in the World War II identification friend or foe (IFF) system, which was code-named "Parrot".

  8. Linear-feedback shift register - Wikipedia

    en.wikipedia.org/wiki/Linear-feedback_shift_register

    A 16-bit Galois LFSR. The register numbers above correspond to the same primitive polynomial as the Fibonacci example but are counted in reverse to the shifting direction. This register also cycles through the maximal number of 65535 states excluding the all-zeroes state. The state ACE1 hex shown will be followed by E270 hex.

    In octal, it would be written 11. Thus, single-digit numbers' primality is easily found just by checking evenness. 3, 5, and 7 would be easily seen as prime, while 4 and 6 would be obviously nonprime. Easy divisibility by 7 and 9: Take a multiple-digit number in octal, such as 527 (decimal 343). Take the sum of the digits (16 octal, 14 decimal ...
