Abstract

Types of signals are introduced first: continuous time and discrete time. Transposition into the frequency domain via the Fourier transform is used to allow for introduction to the signal processing. By manipulation of the spectrum of an example signal the idea of filtering and filters is introduced. Rationale for the relocation of the spectrum by modulation is given. The term and a measure for selectivity are defined and “green design” is introduced.
