■ Formulas for converting measurement data to display parameters
This section describes the formulas for converting the various parameter formats that are
used for measurement and display.
The magnitude of impedance and the phase obtained through measurement at frequency f
[Hz] are Z [Ω] and θ[°], respectively. Furthermore, each parameter is defined as follows.
p =
θ
/ 180 [rad], angular frequency
ω
= 2
f [rad/s]
