Show as plain text (Turkish; formulas and drawings are not included)

Lineer sistemlerden işaretlerin iletilmesi

LTI sistemde çıkışın frekansı giriş ile aynıdır

Enerji ve Enerji yoğunluk fonksiyonu (EYF)

Energy Spectral Density (ESD)

Enerji Tayf yoğunluğu F(EYF)

Enerji işaretleri için özilişki fonk (autocorrelation)

Not: Enerji yoğunluk fonksiyonu max değeri τ=0 'da olurClaude notu: τ=0 ifadesi nedeniyle muhtemelen özilişki fonksiyonu R_x(τ) kastedilmiş.

Güç ve Güç yoğunluk fonk (GYF)

Power Spectral Density (PSD)

EYF, GYF pozitif, reel, çift f.

Güç işaretlerinin özilişki fonk

n_i(t) is noise signal with PSD

Periyodik işaretin öz fonksiyonu periyodiktir
