AI Thread Summary
Resources for understanding spectral density and noise in amplifiers include textbooks on signal processing and electronics that cover equivalent noise bandwidth and transfer functions. Online courses and lecture notes from reputable universities can provide clarity on spectral density, particularly its application and relation to white noise. Key concepts include the significance of root power spectral density in analyzing voltage and current noise. Forums and academic articles may also offer concise explanations and practical examples. These resources can enhance comprehension of complex topics in amplifier noise analysis.

Hey guys

Basically I am doing exam revision and the lecture notes ( and the lecturer) arent that great so i was wondering if you guys could point me to some good resources, specifically those pertaining to the topics below.

1.) equivalent noise bandwidth of an amplifier (or any transfer function)
2.) A bit of info surrounding spectral density. I understand its purpose but have no idea how to use it as it was presented in a very etherial hand waving way. Also SD of white signals (is a white signal white noise?)
3.) Also the significance of the root power spectral density of voltage and current noise with respect that discussed above.

Obviously if any of you guys can give it to me in a nutshell (so you don't have to shpeel if you don't want to) then that'd be great, if not some webpages with some info would be much appriciated.

Cheers
-G

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...
