[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer. He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video ...

Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

The Fourier transform is one of the most fundamental concepts in the information sciences. It’s a method for representing an irregular signal — such as the voltage fluctuations in the wire that ...

An optical imaging system generally consists of an illumination source and a light detection unit. For conventional imaging techniques, a scene is illuminated by a uniform light field and detected ...

No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...
