Spectrum analyzer

A spectrum analyzer is a device that visualizes the different frequencies of signals over a range, showing how strong each frequency is. It’s like a chart that displays the sound or radio waves' various pitches and their intensities. Engineers use it to analyze and troubleshoot electronics, communications, and audio systems, ensuring signals are clear and free of interference. Essentially, it helps identify what frequencies are present and how powerful they are, making it an essential tool for maintaining and optimizing electronic systems.
