Question 4
Modulation Error Ratio is another name for Error Vector Magnitude
SELECT ONE
A True
B False

Solution
4.5(233 votes)

Answer

B False Explanation 1. Define Modulation Error Ratio (MER) MER is a measure of the signal quality in digital modulation, representing the ratio of the average power of the modulated signal to the average power of the error vector. 2. Define Error Vector Magnitude (EVM) EVM quantifies the deviation of the actual transmitted signal from the ideal signal constellation points, expressed as a percentage or dB. 3. Compare Definitions MER and EVM are related but distinct metrics. MER is not another name for EVM; they measure different aspects of signal quality.
