The project is a computer controller spectrum analyzer and clock which was constructed using two light emitting diode on 5×2 matrices. The heart of the device is the Atmel AT90S2313 microcontroller ...

Digital circuitry can produce a wide range of harmonic frequencies and spectrum analyzers can show you this RF frequency spectrum (power or voltage), versus frequency. They are the one piece of gear ...

A hardware device or software used to examine the frequency and power components of a signal. It provides more information than an oscilloscope, because it can display the signals over a range of ...
