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 ...
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 ...
Everything you wanted to know (but were too afraid to ask) about using the MSGEQ7 audio spectrum analyzer chip. I’ve talked about using the MSGEQ7 Spectrum Analyzer chip in several columns over the ...
In the fast-paced world of electronics testing and measurement, spectrum analyzers play a critical role in assessing and understanding radio frequency signals. Many professionals, therefore, choose to ...
The easiest way to envision a spectrum analyzer is to begin with an oscilloscope that plots magnitude versus time. Then swap frequency for time—and voilà—a spectrum analyzer! A gross simplification ...
EE’s electronic test instrument coverage achieved critical mass in the mid-1980s, including a spectrum analyzer story in the August 1986 issue and subsequent August issues into the 1990s and beyond.
