## A Basic Fourier Transform Calculator in Excel – video preview

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] Read More... "A Basic Fourier Transform Calculator in Excel – video preview"

## Spectral Analysis – a Fourier transform tutorial – part #5

This part of the tutorial demonstrates the Fourier transform operation in a few cases of periodic and non-periodic signals, such as an AM signal, an FM signal, a rectangular non repetitive signal and a cardinal sine signal. The last slide contains an application to the scaling property of the Fourier transform on a non-repetitive time signal. It actually shows that… Read More...

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

This is a basic tutorial about implementation of a standard Fourier transform model in Excel. It is not an introduction to Fourier analysis. 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… Read More... "Spectral Analysis – a Fourier transform tutorial – part #1"

## How to Model a Phase-Locked Loop (PLL) in Excel – part#4

This last section of introductory PLL modeling shows how to upgrade the model with adjustable scale charts for three voltage signals within the loop. The model also shows how to create a Lissajous based phase display.
