ADPCM synthesizer without look-up table |
摘要 |
The present invention provides a circuit for use in an ADPCM synthesizer for generating a function of a quantization step without the use of a look-up table. Illustratively, the function is represented in a piecewise linear fashion. This permits an ADPCM synthesizer to be implemented without the use of a memory storing a look-up table for the function so the area of the synthesizer chip can be reduced.
