In this episode of DIY or Buy we will have a short look at commercial function/waveform generators in order to determine what features are important for a DIY version. Afterwards I will then show you how to create a simple function generator, the analog and digital way. At the end I will then present you a DIY DDS function generator design which can (kind of) hold up to the commercial versions. Let's get started!
