WebOct 18, 2024 · When to Use AC Coupling. Use AC coupling if you have a high frequency signal with a DC offset. This could be something like a power rail or a signal with a very low frequency drift. The goal of AC coupling is to remove DC. It’s not intended to remove non-zero, low frequency components. WebIn the AM modulation page, we saw that four things are needed to generate an AM waveform. First, we need a baseband waveform and a carrier waveform. Then we need a circuit that can add an appropriate DC offset to the baseband signal. And finally, we need a multiplier, since the mathematical relationship corresponding to amplitude modulation is ...
