Introduction to Numerical Methods – Basic Filters #2
This post shows the steps for building a first model of a single pole RC high pass filter (HPF) in Excel based on numerical solution using the finite difference method. It is quite elementary to understand, try to go through the proof regardless of your background. [sociallocker][/sociallocker] Basic Filters – Part 2 (1-Pole High Pass Filter) Numerical Solutions to Differential Equations… Read More... "Introduction to Numerical Methods – Basic Filters #2"
Introduction to Numerical Methods – Basic Filters #1
This post shows the steps for building a first model of a single pole RC low pass filter (LPF) in Excel based on numerical solution using the finite difference method. It is quite easy to understand, try to go through the proof regardless of your background.

3-Body Planetary System with Options
Here is a 3-body system with 3D graphics. This model works at about 30 frames/second in Excel 2003 on a modern PC. In Excel 2007 it will run 10-15 times slower. I know 2010 is a lot faster than 2007. I need to add few more features. I am also thinking of adding a 3D gravitational surface map later (like… Read More... "3-Body Planetary System with Options"
Dynamic Lissajous Emulator
This is a dynamic Lissajous emulator in the sense that the waveform is obtained by combining 2 time varying sinusoidal waves with different frequencies. [sociallocker][/sociallocker] Read More... "Dynamic Lissajous Emulator"
Static Lissajous Emulators (2D and 3D)
This is a static Lissajous emulator in the sense that the waveform is obtained by combining 2 static sinusoidal waves with different frequencies. As a parenthesis, I will be preparing a dynamic version which will look just like the wave shape seen on a real oscilloscope. The file presented here has two different worksheets, the first one contains a classic 2D… Read More... "Static Lissajous Emulators (2D and 3D)"

Pendulum
This is a basic pendulum model in Excel. Enjoy! [sociallocker][/sociallocker] This is an animated Excel model of a pendulum that you can download here. For fast modeling speed, please use older versions of excel (1997-2003). In the following section, background information about pendulums in general will be presented: Pendulum meaning, a simple pendulum definition, what is a pendulum? A pendulum… Read More... "Pendulum"
