Frequency Deviation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Frequency Deviation = Frequency Sensitivity*Peak Amplitude of Message
Δf = K_f*A_m(peak)
This formula uses 3 Variables

Variables Used

Frequency Deviation - (Measured in Hertz) - Frequency Deviation in FM is defined as the way to describe the difference between the minimum and maximum extent of a frequency modulated signal and the carrier frequency.
Frequency Sensitivity - (Measured in Hertz) - Frequency Sensitivity is the dependence of the critical amplitude of the signal upon its frequency and a resonance between the intrinsic oscillations of a neuron and the signal.
Peak Amplitude of Message - (Measured in Volt) - Peak Amplitude of Message is the maximum positive or negative deviation of a waveform from its zero reference level in a message signal.

STEP 1: Convert Input(s) to Base Unit

Frequency Sensitivity: 0.75 Hertz --> 0.75 Hertz No Conversion Required
Peak Amplitude of Message: 40 Volt --> 40 Volt No Conversion Required

What is the effect of frequency deviation?

The frequency deviation when combined to the load flow model makes the DTS more realistic but increases the program execution time and computer space, mainly because the load flow Jacobians become nonsymmetric.

How to Calculate Frequency Deviation?

Frequency Deviation calculator uses Frequency Deviation = Frequency Sensitivity*Peak Amplitude of Message to calculate the Frequency Deviation, Frequency Deviation in FM is defined as the way to describe the difference between the minimum and maximum extent of a frequency modulated signal and the carrier frequency. Frequency Deviation is denoted by Δf symbol.
