Abstract
Se revela un aparato de procesamiento de datos para el procesamiento de datos de una senal de audio. El aparato de procesamiento de datos comprendeuna terminal de entrada (1) para recibir la senal de audio, un conversor A/D de 1-bit (4) paraconv ertir A/D la senal de audio para obtener una senal de flujode bit, una unidad de prediccion (10) para llevar a cabo un paso de prediccion en la senal de flujo de bit para obtener una senal de flujo de bit predicha,una unidad de combinacion desenal (42) para combinar la senal de flujo de bit y la senal de flujo de bit predicha para obtener una senal de flujo de bitresidual, y una terminal de salida (14) para proporcionar la senal de flujo de bit residual (Figura 1). Además, se revelan,un apa rato de grabacion (figura 4)y un aparato transmisor (figura 5) comprendiendo un aparato de procesamiento de datos. Pueden encontrarse otros aparatos de procesamiento de datos en lasfiguras 18, 19 y 20. Además, se revela otro aparato deprocesamien to de datos (Figura 7) para convertir la senal de flujo de bit residual en una senal deaudio, así como un aparato reproductor (Figura 9) y un aparato receptor (Figura 10) comprendiendo los otros aparatos de procesamiento dedatos.
