Weak signal measurement Measure low frequency noise signals [Copy link]

Hello everyone, I want to test the low-frequency noise signals of various components in the circuit. How should I describe it in the theoretical part of the paper?

To study these weak signal measurements, low frequency noise signal measurements

At least you should come up with your own so-called theory.

for example:

Analysis of noise sources

Low noise amplification technology
Data acquisition technology
Low noise processing technology

Measurement technology

etc.

The key principles of these technologies are summarized in theory.

It is necessary to carry out some theoretical derivation and establish a simulation model

Add something to attract the instructor's attention

These are the routines of the papers

Unless you really develop some new noise measurement theory and technology

But it's difficult. These things have been played by many professors.

If there are more advanced measuring instruments with higher measurement accuracy, new theoretical technologies can be discovered and researched.
