SELECTIONE
A True
B False b

Solution
4.0(269 votes)

Answer

B False Explanation 1. Define Modulation Error Ratio (MER) MER is a measure of the signal quality in digital modulation, quantifying how much the received signal deviates from the ideal constellation points. 2. Define Error Vector Magnitude (EVM) EVM measures the deviation of the actual received signal from the ideal signal in a constellation diagram, representing the error magnitude. 3. Compare Definitions Both MER and EVM assess signal quality but are distinct metrics; MER is related to power ratio, while EVM is a direct error measurement.
