The circuit has been designed to create a spectrum analyzer that will provide an analysis of a sound to determine at various frequencies, the volume of sounds that make up the overall sound spectrum.
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, ...
Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...
