Abstract: Reproduction accuracy of a digital signal, representing, for example, stereo audio signals, is improved by transmitting sample data which have been encoded to form transmission signals. The stereo audio signals are coded into sub(band) signals. Corresponding sub(band) signals of the stereo audio signals may be processed to obtain composite sub(band) signals, which are recorded on a record carrier. To identify whether corresponding sub(band) signals have been processed or not, a mode indicator control signal, indicating whether a corresponding sub signal of the at least two signal components have or have not been processed into a composite sub-signal, is also being recorded on the record carrier.

Abstract: Reproduction accuracy of a digital signal, representing for example stereo audio signals, is improved by transmitting sample data which have been encoded to form transmission signals. The transmission signals are arranged in consecutive frames, each frame including a plurality of information packets, and each information packet including N bits. The number of information packets in a frame is determined by the ratio of the product of the transmission bit-rate and the number of samples represented in the frame, to the product of the number of bits in a packet and the sampling frequency. The transmission signals are recorded in a record carrier, or are transmitted in real time. In a digital stereo audio signal embodiment, the samples may be sub-band encoded or transform encoded. The transmission signal may include an indicator signal indicating a combination of certain samples, or scale factor signals for specific components of the sampled signal.

Abstract: In a device for determining the weight of a motor vehicle which is being moved by propulsive forces in its longitudinal direction, signals which correlate with a propulsive force and with a corresponding vehicle longitudinal acceleration are recorded with the aid of a sensing system during successive time intervals. Signals recorded at at least two points in time are used by a computer to produce a signal which correlates to the vehicle's weight. To enhance the device's accuracy, signals for the propulsive force and for the corresponding vehicle longitudinal acceleration are detected at successive points in time which follow one another at constant time intervals. The signals in a memory are stored, where they form a time sequence for the propulsive forces and the corresponding vehicle longitudinal accelerations. A plurality of successive stored signals of the time sequence are read from the memory and used to generate the signals that correlate to the current weight of the vehicle.

Abstract: Device for determining the mass of a motor vehicle by determining the running resistance of the vehicle with the clutch in the drive train disengaged, and by repeatedly determining the torque of the engine and, at the same time, repeatedly measuring the vehicle acceleration with the clutch engaged and by taking into account the ratio of the transmission, an average value of the vehicle mass can be determined with a high degree of accuracy.
