  "text": "The bandwidth of the entire combined transducer/recording system shall be no less than 30 Hz.\nIn order to execute the necessary filtering of signals, low-pass filters of fourth order or higher shall be employed. The width of the pass band (from 0 Hz to frequency fo at — 3 dB) shall not be less than 30 Hz. Amplitude errors shall be less than ± 0,5 % in the relevant frequency range of 0 Hz to 30 Hz. All analogue signals shall be processed with filters having sufficiently similar phase characteristics to ensure that time delay differences due to filtering lie within the required accuracy for time measurement.",
