If 𝑥[𝑛]x[n] is instead a real sinusoid according to (3), the magnitude spectrum of 𝑉[𝑘]V[k] exhibits two local maxima (i.e., spectral peaks) that are governed by Dirichlet kernels [55,63], for example of the form sin(𝜃)/sin(𝜃/𝑁)sin(θ)/sin(θ/N) in the...

·(ρu) = 0 (1) That is, the mass conservation equation for an incompressible fluid where ρ is the density (kg/m−3) and u is the 3D velocity vector (m/s) ρ(u·∇u) = −∇P + µ∇2u (2) which is the equation of momentum for Newtonian fluids (constant µ) ...
In order to validate the proposed method without loss of generality, the following gear fault simulation signal based on Equation (11) is studied: s1 = cos(2π f1t + 25) + 0.55 cos(4π f1t + 60) (13) where the mesh frequency is set as f1 = 150 Hz. Meanwhile, the inner race ...
