## Deviation Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
Deviation Ratio = Maximum Frequency Deviation/Maximum Modulating Frequency
D = Δfm/fmax
This formula uses 2 Variables
Variables Used
Maximum Frequency Deviation - Maximum Frequency Deviation the maximum difference between the minimum or maximum extent of a frequency modulated signal, and the nominal center or carrier frequency. (Measured in Kilohertz)
Maximum Modulating Frequency - Maximum Modulating Frequency and the maximum keying frequency are not necessarily equal. (Measured in Kilohertz)
STEP 1: Convert Input(s) to Base Unit
Maximum Frequency Deviation: 75 Kilohertz --> 75000 Hertz (Check conversion here)
Maximum Modulating Frequency: 15 Kilohertz --> 15000 Hertz (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
D = Δfm/fmax --> 75000/15000
Evaluating ... ...
D = 5
STEP 3: Convert Result to Output's Unit
5 --> No Conversion Required
5 <-- Deviation Ratio

Lower Sideband Power
Lower sideband power = (Amplitude of Carrier Signal^2)*(Modulation Index^2)/(8*Resistance) Go
Modulation index with respect to amplitude sensitivity
Modulation Index = Amplitude sensitivity of modulator*Amplitude of modulating signal Go
Amplitude of Modulating Signal
Amplitude of modulating signal = (Maximum amplitude-Minimum amplitude)/2 Go
Transmission Efficiency with respect to Modulation Index
Transmission efficiency = (Modulation Index^2)/(2+(Modulation Index^2)) Go
Amplitude of Carrier Signal
Amplitude of Carrier Signal = (Maximum amplitude+Minimum amplitude)/2 Go
Maximum amplitude
Maximum amplitude = Amplitude of Carrier Signal*(1+Modulation Index) Go
Minimum Amplitude
Minimum amplitude = Amplitude of Carrier Signal*(1-Modulation Index) Go
Upper Sideband Power with respect to carrier power
Upper sideband power = Carrier power*(Modulation Index^2)/4 Go
Lower Sideband Power with respect to carrier power
Lower sideband power = Carrier power*(Modulation Index^2)/4 Go
Amplitude Sensitivity of Modulator
Amplitude sensitivity of modulator = 1/Amplitude of Carrier Signal Go

### Deviation Ratio Formula

Deviation Ratio = Maximum Frequency Deviation/Maximum Modulating Frequency
D = Δfm/fmax

## What determines the amount of deviation of an FM signal?

The amplitude of the modulating signal is converted to frequency variations of the FM ( Frequency Modulation ) signal. These variations are referred to as carrier deviation or deviation.

## How to Calculate Deviation Ratio?

Deviation Ratio calculator uses Deviation Ratio = Maximum Frequency Deviation/Maximum Modulating Frequency to calculate the Deviation Ratio, Deviation Ratio is the ratio of the maximum carrier frequency deviation to the highest audio modulating frequency. Deviation Ratio is denoted by D symbol.
