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
