I am new to signal processing and need little help on discrete and digital data. I have converted analog data to discrete data through LPC vocoder. Now I want to convert discrete data to digital data (binary format 0s and 1s). The question is, how can discrete data (ranging from 0 to 1) be converted into digital data i-e binary format and vice versa. Thanks in advance

Thanks for answer but negative numbers like [-1.234] as de2bi(-1.234) can't be converted into binary. de2bi func only process finite real positive integers.

There is no standard representation for negative binary numbers, other than as IEEE 754 "float" (32 bits) or IEEE 754 "double" (64 bits.)

For any given fixed number of bits, N, there is a minimum of 4*(N-1) different competing representations, one of two of which are very common, one less common but used in hardware implementations, and one very uncommon.

If the number of bits is variable, there is no standard representation, and at least 3 different representations used in practice just to indicate the number of bits, with the choice depending upon the purpose of representation.
