The discussion focuses on the appearance of WiFi and Bluetooth RF waveforms, noting that in the time domain, they appear as a blur during packet transmissions, while in the frequency domain, they show multi-lobed frequency bands. The inquiry stems from either a school assignment or general interest in understanding these waveforms. The thread was moved to the Electrical Engineering forum for broader visibility. Participants engage in questions about the use of oscilloscopes and spectrum analyzers for analyzing communication waveforms. Overall, the conversation highlights the complexities of visualizing RF signals in different domains.

In what domain? In the time domain it looks like a blur during the packet transmissions. In the frequency domain it looks like multi-lobed frequency bands. Is this for a schoolwork assignment or general interest?

Yes.

Yes.
In that case, I'll move the thread to the EE forum to get more views.

@Benjamin_harsh -- Does my post above make sense? Have you used an oscilloscope to look at communication waveforms of any kind? Have you used a spectrum analyzer to look at RF communication bands? :smile:
