Document Summary
Numbers are represented as successive powers of a base or radix. Base of 10, termed the decimal system, most commonly used. Ex: 1324 (1 x 10^3) + (3 x 10^2) + (2 x 10^1) + (4 x 10^0) Base 2, binary system, works with computers 0 and 1. Bit a single digital of a binary number stored in a computer. Byte numbers or computer words are usually stored in these sequences of 8 bits. Least significant bit (lsb) rightmost bit, representing the lowest power. Most significant bit (msb) leftmost bit, representing the highest power. Least significant byte - represents lower powers of the number of 16 or more bits. Most significant byte higher powers of the numbers. Ex: 8-bit system can represent 2^8 (256) values. Hexadecimal number system base 16, often used in computer parlance. Table of some number of points where you can put one cycle of periodic waveform, looping it to get a sound.
