Deviation Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Deviation Ratio = Maximum Frequency Deviation/Maximum Modulating Frequency
D = Δf_m/f_max
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 = Δf_m/f_max --> 75000/15000

Evaluating ... ...

D = 5

STEP 3: Convert Result to Output's Unit

5 --> No Conversion Required

FINAL ANSWER

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 = Δf_m/f_max

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.
