INVISIBLE DICHROIC PHOSPHORESCENT AND FLUORESCENT SYNTHETIC RESIN, AND PREPARATION AND USING METHOD THEREOF |
摘要 |
Audio signals can be converted from analog into digital using the well-known sigma-delta modulation techniques. The digital signal then consists of a sequence of 1-bit samples at a frequency of e.g. 2822400 Hz(=64*44100 Hz). Lossless coding techniques are known to reduce the required storage- or transmission-capacity for these 1-bit oversampled audio signals. With the current invention the performance (compression ratio) of the lossless coder for 1-bit oversampled audio signals can be improved. This is realized by sometimes overruling the probability signal for the lossless coder. |
