Signals in the Frequency Domain

Eugen Georg Woschni

Abstract

Abstract Signals can be mathematically described either in the frequency or in the time domain. Principal methods using the frequency domain are described here. First considered are periodic signals leading to the Fourier spectrum. Discussion then covers nonperiodic signals using the Fourier transform. Also dealt with is the spectral power density of nondeterministic signals, such as random noise.
