What happens if the sensitivity of a digital signal is set too low?

When the sensitivity of a digital signal is set too low, it can result in waveforms being clipped. This occurs because the low sensitivity setting means that the system cannot adequately capture the full amplitude of the signals. If the incoming signal amplitude exceeds the maximum level that the system can register due to the low sensitivity, the peaks of the waveform will be truncated, causing distortion. This clipping effect leads to a loss of important signal information, particularly in high amplitude transients, and can significantly affect the accuracy and quality of the digital representation of the signal.

In contrast, other options such as aliasing, altered frequency response, and affected Common Mode Rejection Ratio (CMRR) are related to different issues in signal processing and instrumentation that do not directly result from sensitivity settings.
