The sampling process,es, if the frequency content of the signal to be sampled contains no energy at and above half of the sampling frequency (sampling theorem). We will investigate what happens if we deliberately violate this rule (aliasing effect).

The digital anti-alias filter,lias filters with very steep transition bands are needed to obtain the best resolution for a given frequency band of interest. The filter should also leave a band-limited signal which falls completely within the passband as unaffected as possible, causing neither amplitude nor phase distortions.

Frank Scherbaumrves both organised and opportunistic goals as “dual purpose” criminality. Ordinary, political or indeed dual purpose criminality effectively acts as a border policing apparatus that controls women’s mobility, thus gatekeeping women’s access to other countries, and in many cases access to legal reme

From infinitely continuous to finite discrete,o far. We will see for example that the transition from continuous-time to discrete-time systems corresponds to a transition from aperiodic to periodic Fourier spectra. This property for example will allow us to take a new look at the aliasing problem. Furthermore, we will meet the z-transform for d
