In digital systems, poor signal quality can lead to inaccurate measurements and data. This happens because digital systems rely heavily on precise and clear signals to properly interpret and process information. When the signal is degraded due to noise, distortion, or interference, the system may misinterpret the data it receives.

For instance, in digital communications, if a signal is weak or corrupted, the receiving device might incorrectly decode the information being transmitted, which can lead to errors. Such inaccuracies can have significant impacts, especially in applications that require high precision, such as medical monitoring, data transmission, or any critical measurements.

The other options do not describe the effects of poor signal quality accurately. For example, higher data storage capability and increased processing speed are not direct consequences of poor signal quality. Additionally, enhanced electrical safety does not relate to signal quality but rather to the design and regulation of electrical systems. Hence, the answer focusing on inaccurate measurements and data correctly highlights the critical challenge that poor signal quality presents within digital systems.
