## Error Vector Magnitude using RMS Voltage Solution

STEP 0: Pre-Calculation Summary
Formula Used
Error Vector Magnitude Using Rms Voltage = (1/Rms Voltage of the Signal)*sqrt((1/Number of Error Vectors)*sum(x,1,Number of Error Vectors,(Magnitude of Each Error Vector)^2))
EVM1 = (1/Vrms)*sqrt((1/N)*sum(x,1,N,(ej)^2))
This formula uses 2 Functions, 4 Variables
Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
sum - Summation or sigma (∑) notation is a method used to write out a long sum in a concise way., sum(i, from, to, expr)
Variables Used
Error Vector Magnitude Using Rms Voltage - Error Vector Magnitude Using Rms Voltage to represent the deviation of the constellation points from their ideal positions.
Rms Voltage of the Signal - (Measured in Volt) - Rms Voltage of the Signal is a measure of the effective voltage level of the signal over a certain period of time.
Number of Error Vectors - Number of Error Vectors is the count of vectors that are drawn between each measured point and its ideal position.
Magnitude of Each Error Vector - (Measured in Meter) - Magnitude of Each Error Vector is a measure of the absolute size or length of the error in a vector space.
STEP 1: Convert Input(s) to Base Unit
Rms Voltage of the Signal: 5.25 Volt --> 5.25 Volt No Conversion Required
Number of Error Vectors: 9 --> No Conversion Required
Magnitude of Each Error Vector: 8 Meter --> 8 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
EVM1 = (1/Vrms)*sqrt((1/N)*sum(x,1,N,(ej)^2)) --> (1/5.25)*sqrt((1/9)*sum(x,1,9,(8)^2))
Evaluating ... ...

Error Vector Magnitude Using Average Power = (1/Average Signal Power)*(1/Number of Error Vectors)*sum(x,1,Number of Error Vectors,(Magnitude of Each Error Vector)^2)
Bandwidth with respect to Modulation Index of FM
Bandwidth of FM Wave = (2*Frequency Deviation)*(1+(1/Modulation Index in FM))
Bandwidth of FM by Carson Rule with Beta
Bandwidth of FM Wave = 2*(1+Modulation Index in FM)*Modulating Frequency
Frequency Sensitivity
Frequency Sensitivity = Frequency Deviation/Peak Amplitude of Message
Frequency Deviation
Frequency Deviation = Frequency Sensitivity*Peak Amplitude of Message
Bandwidth of FM wave by Carson Rule
Bandwidth of FM Wave = 2*(Frequency Deviation+Modulating Frequency)
Frequency Deviation provided Modulation Index
Frequency Deviation = Modulation Index in FM*Modulating Frequency
Modulation Index of FM Wave
Modulation Index in FM = Frequency Deviation/Modulating Frequency
Modulating Frequency
Modulating Frequency = Angular Frequency/(2*pi)

## What is the purpose of calculating the Error Vector Magnitude using RMS Voltage?

The constellation can also provide a quantitative measure of the impairments that corrupt the signal. Representing the deviation of the constellation points from their ideal
positions, the “error vector magnitude” (EVM) is such a measure. To obtain the EVM,
a constellation based on a large number of detected samples is constructed and a vector is
drawn between each measured point and its ideal position. The EVM is defined
as the rms magnitude of these error vectors normalized to the signal rms voltage.
