# Description

In the course of solving the following tasks:
Run polynomial approximation CVC II degree (select operation
site and to determine the coefficients of approximation).
2. Determine the circuit current i (t) and the spectrum of the current under the action of a harmonic In
signal () cos () 0u t V tc = ω (V is selected within the working area) at a power
approximation of the CVC.
Build temporal and spectral chart of current.
3. Determine the current in the circuit i (t) and the range of current In at Biharmonic
exposure through the power approximation CVC.
Build temporal and spectral chart of current.
4. Perform piecewise linear approximation of the CVC (select operation
the site and determine the slope of the current-voltage characteristics - S and the cut-off voltage - Un).
5. Determine the current in the circuit i (t) and current range In the case of piecewise-linear
approximation and the two corners of the cut-off: θ = 60 ° and θ = 90 °.
Build temporal and spectral chart of current.
