An oscilloscope captures and displays signals in the time domain, while a spectrum analyzer captures and displays signals in the frequency domain. Sometimes, oscilloscopes have a built-in spectrum analyzer function to make it easy to analyze signals in both the time and frequency domains.
You can build a DC power supply by converting AC to DC using an AC-DC converter or rectifier, and then using a voltage regulator to maintain a stable output voltage. The basic steps for constructing a DC power supply are as follows: Please note that constructing a power supply requires familiarity with electronic and electrical safety. It is best to consult a professional or use a pre-built kit to avoid danger. ,
