  3. Digital pattern generator - Wikipedia

    en.wikipedia.org/wiki/Digital_pattern_generator

    The number of digital channels defines the maximum width of any pattern generated - typically, 8-bit, 16-bit, or 32-bit pattern generator. A 16-bit pattern generator is able to generate arbitrary digital samples on any number of bits from 1 to 16. The maximum rate defines the minimum time interval between 2 successive patterns. For instance, a ...

    en.wikipedia.org/wiki/Star_number

    A star prime is a star number that is prime. The first few star primes (sequence A083577 in the OEIS) are 13, 37, 73, 181, 337, 433, 541, 661, 937. A superstar prime is a star prime whose prime index is also a star number. The first two such numbers are 661 and 1750255921. A reverse superstar prime is a star number whose index is a star prime ...

    Lavarand, also known as the Wall of Entropy, is a hardware random number generator designed by Silicon Graphics that worked by taking pictures of the patterns made by the floating material in lava lamps, extracting random data from the pictures, and using the result to seed a pseudorandom number generator.
