In this paper, we propose a novel method for estimating the parameters (frequency, amplitude, and phase) of real sinusoids. To derive the estimator, we start from the characteristic differential equation of a sinusoid. To remove differentials and obtain an algebraic relation for frequency, we intr...
Simulation of Mathieu equation; unstable response σ=4,∊1=0,ω=π/4 In this case we deal with the well-known equation ϕ¨+δϕ=0 whose solution is a sinusoid with circular frequency δ: ϕ=C1sinδt+C2 The constants C1,C2 can be found from the initial conditions of the ...
Short-Time Frequency Estimation of a Real Sinusoid(Digital Signal Processing) The frequency estimate for a real sinusoid provided by the periodogram has a bias which is particularly severe for a short observation interval. In this pa... SO Hing-Cheung,YT Chan - 《Ieice Transactions on Fundamental...
Figure 2 illustrates the maximum displacement of a sinusoid wave. This is the wave's amplitude, and it can be described by rearranging the equation for the position of a wave. The position of a wave exhibiting simple harmonic motion can be described using the SHM equation, x=Asin(ωt) whe...
To do this, take the first sample from each sinusoid and add them together. The sum must be equal to the first sample in the time domain signal, thus providing the first equation. Likewise, an equation can be written for each of the remaining points in the time domain signal, resulting ...

A sinusoid would be ideal because the derivative or integral of a sinusoid is still a sinusoid, only the amplitude and phase would be different. This approach is illustrated in Figure 5.6. So our strategy will be to input a number of sine waves having different amplitudes. If the output ...
