Deviation Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Deviation Ratio = Maximum Frequency Deviation/Maximum Modulating Frequency
D = Δf_m/f_m
This formula uses 3 Variables

Variables Used

Deviation Ratio - Deviation Ratio is the ratio of the maximum carrier frequency deviation to the highest audio modulating frequency.
Maximum Frequency Deviation - (Measured in Hertz) - Maximum Frequency Deviation the maximum difference between the minimum or maximum extent of a frequency modulated signal, and the nominal center or carrier frequency.
Maximum Modulating Frequency - (Measured in Hertz) - Maximum Modulating Frequency and the maximum keying frequency are not necessarily equal.

STEP 1: Convert Input(s) to Base Unit

Maximum Frequency Deviation: 750 Hertz --> 750 Hertz No Conversion Required
Maximum Modulating Frequency: 15000 Hertz --> 15000 Hertz No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = Δf_m/f_m --> 750/15000

Evaluating ... ...

D = 0.05

STEP 3: Convert Result to Output's Unit

0.05 --> No Conversion Required

FINAL ANSWER

0.05 <-- Deviation Ratio

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.

How to calculate Deviation Ratio using this online calculator? To use this online calculator for Deviation Ratio, enter Maximum Frequency Deviation (Δf_m) & Maximum Modulating Frequency (f_m) and hit the calculate button. Here is how the Deviation Ratio calculation can be explained with given input values -> 0.05 = 750/15000.

FAQ

What is Deviation Ratio?

Deviation Ratio is the ratio of the maximum carrier frequency deviation to the highest audio modulating frequency and is represented as D = Δf_m/f_m or Deviation Ratio = Maximum Frequency Deviation/Maximum Modulating Frequency. Maximum Frequency Deviation the maximum difference between the minimum or maximum extent of a frequency modulated signal, and the nominal center or carrier frequency & Maximum Modulating Frequency and the maximum keying frequency are not necessarily equal.

How to calculate Deviation Ratio?

Deviation Ratio is the ratio of the maximum carrier frequency deviation to the highest audio modulating frequency is calculated using Deviation Ratio = Maximum Frequency Deviation/Maximum Modulating Frequency. To calculate Deviation Ratio, you need Maximum Frequency Deviation (Δf_m) & Maximum Modulating Frequency (f_m). With our tool, you need to enter the respective value for Maximum Frequency Deviation & Maximum Modulating Frequency and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
