PURPOSE:To prevent a sound signal which is errorneously decoded on a reception side from being made into noise without deteriorating a transmission rate in the transmission system of the sound signal and a data signal by means of an encoding/decoding system. CONSTITUTION:This digital communication system inserts plural energy bits corresponding to parameter deciding sound volume at every frame of a sound into a transmission side as a silent code word and removes it and allows a noise signal to be silent on the reception side. |
