Function Generator

This is a quick demonstration of my Function Generator project at hte end of my First year of Electronic Engineering at Uni. It doesn't work at the moment, but that's purely because I'm yet to get the SPI communication working. :(

It uses an AD9834 to create sine, square and triangle waveforms through DDS. It has a theoretical bandwidth of 25MHz, but anything above 1MHz needs filters to remove the noise.

Inside the case is an Arduino Which handles the controls and the SPI communications.
