Laboratorium 2 - 9.11.2010 - korelacja

Korelacja - podobieństwo dwóch zjawisk (np. sygnalow, jak jeden jest podobny do drugiego)

Korelacja wzajemna (dla 2), autokorelacja (dla 1)

R_{xx}(\tau) = E[x(t)x(t+\tau)]

R_{x,y}(\tau) = E[x(t)y(t+\tau)]

Laboratorum nr 3 - 23.11.2010 - Probkowanie i kwantowanie

1. Probkowanie
sinus
a) fpr > 2*f
b) fpr == 2*f
c) fpr < f

Jak wyglada sygnal w dziedzinie czasu i czestotliwosci?

Dyskretna transformata Fouriera

1. sinus
wyznaczyc widmo dla sygnalu ktory 
a) w n probkach bedzie mial calkowita liczbe okresow
b) w n probkach bedzie mial niecalkowita liczbe okresow
fft/g + semilogy -> widmo

2. dyskretna transformata Fouriera (probkowanie widma ciaglego)
a) f_sin \in m*fpr/N, m \in {0,1,..,N-1}

So this happened: phrack changed it's format and posted a nice analysis of the 
(nowadays missing) hacker community and societal behaviour of hackers in

This article reflects a lot of thoughts I've had over the last couple of 
months. In a very positive way.
 
 
Yea sure, the scene we grew up in changed to what has now become a bullshit 
business like any other. Originality is scarce and every time I see SQLi or
