All signals in a given group are stored in the same file. If there are two or more signals in a group, the file is called a multiplexed signal file . All signals belonging to the same group must be stored in the same format. For ordinary disk files, bsize is zero.
All signals belonging to a given group have the same bsize .
Typical ADCs have resolutions between 8 and 16 bits inclusive. For the MIT DB, however, an offset binary ADC was used, and adczero was 1024. All signals in a given record must have the same number of samples. Input and output signal numbers are assigned beginning with 0 in the order in which the signals are given in siarray . Note that input signal 0 and output signal 0 are distinct.
