[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 ...

There are many ways to look at the world, and many ways to look at electronic signals. Many fundamental instruments, such as voltmeters and oscilloscopes, use a time-oriented approach. They provide ...

This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor. This audio ...
