The modulation error proportion is an action used to measure the exhibition of a computerized radio transmitter or recipient in a transmission framework utilizing digital modulation. MER is a measure of the signal-to-noise ratio (SNR) in digital modulation applications. These kinds of estimations are helpful for deciding framework execution in communications applications. The unit of measure for MER is decibels (dB). A more elevated level of MER demonstrates lower level of impairments and higher quality and vice versa.
