Sound-level measurements offer a conventional way to measure sound but do not contain frequency information, making it difficult to compare different sounds or vibration. Octave analysis filters the ...

In this article, we will explore AC analysis with the “.AC” directive, one of the main techniques for evaluating the frequency response of circuits. It is one of the most powerful features of SPICE ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
