•What is noise?
•Waveforms with
incomplete information
–Analysis: how?
–What can we
determine?
•Example: sine waves of
unknown phase
–Energy Spectral
Density
–Probability
distribution function: P(v)
–Probability density
function: p(v)
–Averages
•Common probability
density functions
–Gaussian
–Exponential
