Which consequence results from exceeding guard band limits caused by imperfect frequency synchronization in a multiplexed telecommunications system?

💡 Explanation

Adjacent channel interference appears because imperfect frequency synchronization causes spectral leakage; the guard band's function against overlap becomes compromised because of an increase the inter-channel interference, therefore degrading signal quality rather than any change in bit rate, latency, or power usage.
