Title:
差分コーディング原理を用いる送信システム
Document Type and Number:
Japanese Patent JP3827720
Kind Code:
B2
Abstract:
In a transmission system for transmitting speech and music signals, an input signal is coded in a coder (11) by a time domain coder (4). The output signal of the time domain coder (4) is decoded by a time domain decoder (8) and the signal thus decoded is subtracted from the input signal by a subtracter circuit (10). To improve the coding quality, the difference signal is coded by a frequency domain coder (12) and the output signal of the time domain coder (4) and of the frequency domain coder (12) is combined in a multiplexer (14) and transmitted to a receiver. 00000
