Bandwidth Frequency given Damping Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
Bandwidth Frequency = Natural Frequency of Oscillation*(sqrt(1-(2*Damping Ratio^2))+sqrt(Damping Ratio^4-(4*Damping Ratio^2)+2))
fb = ωn*(sqrt(1-(2*ζ^2))+sqrt(ζ^4-(4*ζ^2)+2))
This formula uses 1 Functions, 3 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)
Variables Used
Bandwidth Frequency - (Measured in Hertz) - Bandwidth Frequency is the range of frequencies over which, the magnitude of frequency domain drops to 70.7% from its zero frequency value.
Natural Frequency of Oscillation - (Measured in Hertz) - The Natural Frequency of Oscillation refers to the frequency at which a physical system or structure will oscillate or vibrate when it is disturbed from its equilibrium position.
Damping Ratio - Damping Ratio in control system is defined as the ratio with which any signal gets decayed.
STEP 1: Convert Input(s) to Base Unit
Natural Frequency of Oscillation: 23 Hertz --> 23 Hertz No Conversion Required
Damping Ratio: 0.1 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
fb = ωn*(sqrt(1-(2*ζ^2))+sqrt(ζ^4-(4*ζ^2)+2)) --> 23*(sqrt(1-(2*0.1^2))+sqrt(0.1^4-(4*0.1^2)+2))
Evaluating ... ...
fb = 54.9696597723011
STEP 3: Convert Result to Output's Unit
54.9696597723011 Hertz --> No Conversion Required
FINAL ANSWER
54.9696597723011 54.96966 Hertz <-- Bandwidth Frequency
