When Do You Use W 2*pi*frequency – The velocity formula is used to find the frequency of the wave. Efficiency is defined as the number of cycles completed per unit time. It also tells how many shells pass a given point in a given time. Sometimes called time interaction. Frequency is expressed in Hertz (Hz). The velocity formula is used to find the frequency of the wave. Let’s understand better using solved examples.
Frequency is the total number of occurrences per unit time. There are various frequency formulas for calculating frequency based on specific quantities. The wave frequency formula is used to find frequency (f), time period (T), wave speed (V) and wavelength (λ). 1 hertz is one cycle per second.

Example 1: Find the frequency of a wave that completes one revolution in 0.5 seconds using the frequency formula.
A frequency formula is defined as a formula for finding the frequency of a wave. The formula for frequency is frequency (f), time period (T), wave speed (V) and wavelength (λ).
In the velocity formula, f = 1/T, where T is the time period. T represents the time to complete one cycle (in seconds). Time duration is inversely proportional to frequency.

However, I’m pretty sure the equation for n is wrong because cosine is the square and n/fs is the square root. This equation does not produce a period for each omega value (I assume between 100 Hz and 12 kHz).
I don’t know if fs is actually equal to f, since it should be governed by the length of n. Is it true of one or both of these factors?
Another problem I have is that if the peak frequency BF is 12 kHz, fs = 20 kHz, it causes some isolation. Should I remove frequency bands above 10 kHz?
My final problem is that, considering the equation, it seems that the filter does not have a high fs to represent very high frequencies, so the length of n goes to 0 before 10kHz.

Any help correcting my implementation or finding a typo in the paper would be appreciated. thank you
I’m still worried about the sample rate, but I don’t know how to solve it without the filter being inconsistent with the data I’m using.
I may be off the mark, but I think there is an error in the paper or no error at all. However, if you subtract $f_s$ from the $f$ equation as shown and use the *normalized* angular frequency, i.e. $omega = 2pi f/f_s$ , you get something very close (normalized) to what you are looking for.

3 Free Oscillations We can neglect frictional forces. In this case, the oscillator continues to oscillate to a certain extent. It is suitable for small movements
5 Position Time – The position (x) of a simple harmonic oscillator is sinusoidal. Where we begin to measure is baseless.

Frequency Instead Of Phase
9 Angular frequency 𝜔 = 2𝜋 𝑇 𝜔 = 2𝜋𝑓 → 𝑓 = 𝜔 2𝜋 So angular frequency is the number of complete oscillations per unit time.
The phase difference of a complete sine wave is a radius of 2π. One wave lags the other by a full half cycle with a phase difference.
