Building home or very small small office electronic-circuit prototypes, part 1. The author writes, “This is hopefully the first installment of several related to setting up a small and inexpensive hobbyist/limited-technology-prototype build-and-test capability.” Unfortunately, I don’t think that there’s a part two, even though this was written a year ago. Even so, it’s an interesting story of how this engineer set up a small surface mount reflow oven.
What is the piezoelectric effect? A short, basic introduction to piezoelectricity: who discovered it, how it works, and what piezoelectric devices are still used in electronics devices today.
FFT: equations and history. The FFT (Fast Fourier Transform) is rightfully regarded as the most important numerical algorithm of our lifetime. Whether it’s used to monitor signals coming from the depths of the earth or search for heavenly life forms, the algorithm is widely used in all scientific and engineering fields. But,what exactly is an FFT? How is it used in software-defined radios?
