SUMMARY

This discussion focuses on understanding spectral density and noise in amplifiers, specifically the equivalent noise bandwidth of an amplifier, the application of spectral density, and the significance of root power spectral density of voltage and current noise. Participants emphasize the need for clear resources to grasp these concepts, particularly in relation to transfer functions and white noise. The discussion highlights the confusion surrounding the practical application of spectral density and its relationship to white signals.

PREREQUISITES
  • Understanding of amplifier theory and transfer functions
  • Familiarity with noise concepts in electrical engineering
  • Basic knowledge of spectral density and its applications
  • Concept of white noise and its characteristics
NEXT STEPS
  • Research equivalent noise bandwidth in amplifiers
  • Study the practical applications of spectral density in signal processing
  • Explore the relationship between white noise and spectral density
  • Learn about root power spectral density and its significance in noise analysis
USEFUL FOR

Electrical engineers, students studying amplifier design, and anyone interested in noise analysis and spectral density in signal processing.

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
