EE Pac

The Electrical Engineering (EE) Pac provides fourteen modules that calculate different functions for power, impedance, reactance, delta-wye circuits, attenuators, RC and RL timing, RLC circuits, network transforms, Fourier series, active filters, transmission lines, base conversions and matrix operations.

The user interface provides an intuitive input view with validation of range values and necessary input parameters. The output is presented in an easily comprehendible format.

Power module calculates direct current (DC) and alternating current (AC) power and solves for parameters of Ohm’s Law.

Reactance Calculator module determines the resonate frequency, capacitive reactance, inductive reactance, inductance or capacitance for combinations of these parameters.

Impedance Calculator module evaluates the equivalent complex impedance of serial or parallel complex impedance network elements. The complex impedance parameters can be input in one of two possible parameter formats – rectangular or polar.

Delta-Wye Transform module translates a delta or wye impedance load configuration into the corresponding other equivalent complex impedance load configuration. The complex impedance parameters can be input in one of two possible parameter formats – rectangular or polar.

Reactive-L Network Impedance Matching module calculates reactive only elements to transform a complex impedance source into a complex impedance load.

Resistive Attenuator module provides two functions for calculating either a
T attenuator or a PI attenuator that can be used to match between two resistive impedances.

Network Transfer Function module calculates various transfer functions of a ladder network composed of any number of resistor, inductor or capacitor components.

RC and RL Circuits module solves for variables of resistor and capacitor (RC) or resistor and inductor (RL) circuits. Two options for calculations are provided – time and time series.

RLC Circuits module solves for variables of a serial or parallel circuit consisting of a resistor, an inductor and a capacitor (RLC). Two options for calculations are provided – time and time series.

Active Filter Design module calculates circuit elements for low pass, high pass and band pass filters. The filter design depends on the corner or center frequency (f0), mid band gain (A), peaking factor (alpha) and a capacitor (C).

Transmission Line Impedance module determines the high frequency characteristic impedance for an open two-wire line, single wire near ground, balanced wires near ground, wires in parallel near ground and coaxial lines.

Discrete Fourier Series module calculates the discrete Fourier series for a periodic function. The Fourier series consists of sine and cosine terms (rectangular form) or only sine terms (polar form) that combine to approximate the periodic function.

Base Conversions module converts a positive number in one base into its equivalent in another base. The bases can be any integer value from 2 to 36.

Matrix Operations module provides basic, arithmetic and solution functions for NxN matrices, where the size is between 2 and 50 inclusive. The basic matrix functions include determinate, inverse matrix and transpose matrix functions. The arithmetic functions provide addition, subtraction and multiplication calculations. The program also calculates solutions for linear equations where there are an equal number of equations and unknowns.
