What is the adverse effect of electromagnetic interference in communication systems?

Electromagnetic interference (EMI) adversely affects communication systems primarily by disrupting signal integrity. When EMI occurs, it can introduce unwanted signals or noise into the system, leading to degradation of the original signal. This disruption can result in data loss, errors in communication, and overall reduction in the quality of the transmitted information. It compromises the clarity of the signals being sent and received, making it challenging to maintain consistent and reliable communication. Maintaining signal integrity is crucial for effective transmission of data, and interference can severely hinder this process.

Options suggesting improvements or enhancements, such as increased data continuity or enhanced clarity, directly contradict the nature of EMI, which is fundamentally a source of degradation rather than enhancement. Increased power consumption might occur in systems experiencing interference due to the need for additional error-correcting measures, but that doesn't define the primary adverse effect of EMI itself.
