From the point of view of statistical signal processing, the dynamic range for one‐bit quantisers with time‐varying thresholds is studied. Maximum tolerable amplitudes, minimum detectable amplitudes and dynamic ranges of this one‐bit sampling approach and uniform quantisers, such as N ‐bits analogue‐to‐digital converters (ADCs), are derived and simulated. The results reveal that like conventional ADCs, the dynamic ranges of one‐bit sampling approach are linearly proportional to the Gaussian noise standard deviations, while one‐bit sampling's dynamic ranges are lower than N ‐bits ADC under the same noise levels.
