1. A method of operating a first-in first-out (FIFO) memory arranged to store measurement data samples measured by a plurality of data measurement sensors, in which memory an oldest measurement data sample is arranged to be read first, the method comprising:

  • sampling first measurement data samples from a first measurement sensor of a first type at a first sampling rate and second measurement samples from a second measurement sensor of a second type at a second sampling rate different from the first sampling rate;

    storing the first measurement data samples in the FIFO memoryin association with a first tag that identifies the first data measurement sensor based on the sampling of the first measurement data samples at the first sampling rate; and

    storing the second measurement data samples in the FIFO memory in association with a second tag that identifies the second data measurement samples based on the sampling of the second measurement data samples at the second sampling rate.
