41. In a digital system, a more precise representation of a signal can be obtained by using more binary digits to represent it. 42. The range of possible values that can be represented numerically by a sample is defined by the number of binary digits used. 43. It is a little dramatic to watch a person get 40 binary digits in a row and then repeat them back without error. 44. So for instance the \ scriptstyle 4 \ cdot10 ^ { 13 }-th binary digit of \ pi is known to be 0. 45. A similar relationship holds between every octal digit and every possible sequence of three binary digits , since eight is the cube of two. 46. Bernett himself can memorise a pack of cards in three minutes, 160 random numbers in five minutes and 300 binary digits in five minutes. 47. With three binary digits , gray code ( or any other code for that matter ) can encode 2 3 = 8 positions at most: 48. Positional systems obtained by grouping binary digits by three ( octal numeral system ) or four ( hexadecimal numeral system ) are commonly used. 49. A bit, in case you have ever wondered, is the smallest unit of computer information storage, and its name is short for binary digit . 50. The oscillation can be made to represent a binary digit by the choice between two stationary phases ? radians ( 180 degrees ) apart.
