This is a video preview of the Fourier transform model presented on this blog before. A tutorial explaining the creation of such a model was posted here too. [sociallocker][/sociallocker]

#### Spectral Analysis – a Fourier transform tutorial – part #1

03/28/2011

This is a basic tutorial about implementation of a standard Fourier transform model in Excel. It is not an introduction to Fourier analyis. You could choose to familiarize yourself with the subject before proceeding with this tutorial. Solving a few Fourier transform excersises would be of help too. Essentially, this part shows you how to adapt the general Fourier formula for a continuous real signal to a sampled signal having a limited number of samples.

#### Tutorial – a Static Lissajous Emulator

12/11/2010

Hi there, this is a tutorial explaining the construction of a very basic Lissajous emulator in Excel. It’s supposed to be very easy to understand at the high school level.  Good luck, George [sociallocker][/sociallocker]

#### Dynamic Lissajous Emulator

10/01/2010

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]

#### Static Lissajous Emulators (2D and 3D)

09/29/2010

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 paranthesis, 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 Lissajous figure and the second one has a 3D Lissajous pattern obtained from three different…
