Spectral Estimation and Adaptive Signal Processing

Checklist

1. I know what a spectrum is
2. I know how to find a signal's power spectral density
3. I know a power spectral density is the fourier transform of an autocorrelation
4. I know how to find it's estimator
5. I think I know how to prove its bias and variance
6. I don't know much else, so Wednesday is not going to be a good day

I also figured out the difference between IIR and FIR filters yesterday. I am screwed!
