How effective is cable shielding?

Cable shielding uses either a braided, spiral design or metal-coated Mylar or foil shield. The shielding wraps around each conductor to mitigate noise by 85% to 100%, depending on the configuration. The maximum shielding a braided shield can have is 90%.

What does this impedance function represent?

The impedance function, Ζ(ω), is the inverse of the admittance function: Ζ(ω) = [Υ*(ω)]- 1 Since both the amplitude and phase angle (|Y(ω)| and ϕ, respectively) of the output may change with respect to the input values, the impedance is expressed as a complex number: Z = Zreal + jZimg, where Zreal is the real part and …
