It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina Neumryr]’s niche comes in building projects from old electronics magazines, and ...

If you have a modern function generator on your bench it is quite likely to contain a direct-digital synthesis circuit that creates arbitrary waveforms using a microprocessor controlled DAC. If you ...

A description of a four-phase RC oscillator of a sinusoidal and rectangular shape is given. A triangular-shaped signal is obtained by the counterphase addition of half-waves of sinusoidal signals ...

If you ask a hundred engineers who created the commercial function generator, at least 99 will tell you it was Wavetek — which was not quite the case. It's close, but there are several people who ...

Bioengineers who specialize in creating tools for synthetic biology have unveiled the latest version of their 'biofunction generator and bioscilloscope,' an optogenetic platform that uses light to ...
