Most of my Blog posts involve short 3-4 hour projects/hacks that I just build up for learning and fun. I thought it was time to develop something a bit more involved and share my design process in a ...

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables, and other ...

A Microchip PIC16F628 is used as the controller chip for this low cost and simple Since/Square wave generator based on the Analog Devices AD9835 Direct Digital Synthesis (DDS) Generator chip. The ...

Your circuit prototype finally is complete, and now you need a signal source to test it. The function generator is a good choice. It can provide sine, square, and triangular waveforms from fractions ...

Function generator based on the AD9833 DDS chip and CH32V003F4P6 MCU. Outputs sine, triangle, and square waves with frequencies up to ~1 MHz. Amplitude up to 3.7 V for sine and triangle, 5 V for ...

A lifetime of amassing random pieces of test equipment has left me with a gap in my armoury, namely that I don’t possess a low frequency function generator. This could easily be addressed, but for two ...

Function generators are a handy bench tool to have around, and while you can usually cobble something together that works, it is much more handy to grab a device when you need it. Thats where this ...
