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:
 

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
