Abstract: PURPOSE:To effectively use a coding system and to improve the transmission efficiency of a data signal by transmitting and receiving data by judging error status in a line and selecting respective coding means and decoding means which are optimum for the line. CONSTITUTION:At a calling station, a transmitting system is actuated by the control of a control part 11, and a line status signal is transmitted from an antenna 1 through a coder 6 for correcting one error and a transmitting part 3 to a called station. At the called station, the line status signal is received at the antenna 1, and the received line status signal is taken through a receiver part 4 and a decoder 9 for correcting one error into the control part 11. the control part 11 judges the existence of an error in the corrected signal and transmits a switching information signal from the antenna 1 through the coder 6 and the transmitting part 3 to the calling station. The calling station control part 11 takes in the received signal, judges whether the information is detected information or corrected information, switches to the sides of a coder 7 for detecting one error and a one error decoder 8 when the information is the detected information, and switches to the sides of the coder 6 and the decoder 9 when the information is the corrected information.

Abstract: PURPOSE:To enable an air conditioning system to be simplified, reduce expenditure and further enable an efficient sound muffling to be carried out by a method wherein duct systems are grouped for rooms not requiring any concurrent sound muffling and there are provided a system changing-over unit and a control unit for every grouped system. CONSTITUTION:Noise (primary sound) transmitted within a duct 1 is measured by a sensor microphone 2. Control units 5-A and 5-B control secondary sound produced by a loud speaker 3 through system converting units 6-A and 6-B in response to the measured value, a signal is sent to the loud speaker 3, the secondary sound is produced within the duct 1 and overlapped with the primary sound. The primary sound is muffled under this overlapping action. However, in the case that there still remains noise not completely muffled, this noise is caught by an error microphone 4 and the secondary sound produced by the loud speaker 3 is controlled (fed back controlled) in response to the measured value of the noise. With such an arrangement, it is possible to simplify the facility, reduce expenditure and muffle noise efficiently.
