Signal Detection and Noise

Course 2014-2015


The goal of this course is to learn how to properly measure a signal, to understand sources of noise and to cope with them. For this, we offer a combination of theory (lectures), exercises and practical lab work.


• Electronic circuits
Transfer functions, complex impedances, Bode-Plots, Step Response functions
• Fourier Transforms and digital processing
Convolution, Discrete Fourier Transform, Modulation, Aliasing, Analog/Digital conversion
• Noise
Noise spectral density, Johnson Noise, Shot Noise, Wiener-Khinchin theorem, Noise reduction
• Feedback and basic system analysis
Negative and positive feedback, Stability criterion, Laplace Transform
• Operational Amplifiers
Inverting amplifier, Differentiator, Integrator; Non-ideal OpAmp

Programme form

Lectures, excercises and lab work


Lecture notes Signal Detection and Noise and background information provided on Blackboard.



Remark:it is possible that just a single practical group is formed when the size of the group allows this


Lab work, homework (on-line tests) and exam (mid-term exam)


Generally: knowledge of Fourier Transforms, Experimental experience, being familiar with Labview software
The following Leiden courses are prerequisites:
Experimentele Natuurkunde, Natuurkundig Onderzoek, Labview, Analyse 3 NA (Fourier Transforms)
If you have not studied in Leiden, but have followed equivalent courses, please contact the lecturer.
