AI Thread Summary
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:
 
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'
I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
