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 dont think that theres a part two, even though this was
written a year ago. Even so, its an interesting story of how this engineer
set up a small surface mount reflowÂ*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.Â*The FFT (Fast Fourier Transform) is rightfully
regarded as the most important numerical algorithm of our lifetime. Whether
its 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?Â*How is it used in
software-defined radios?
