This Topic is a very brief introduction to the idea of native
discretetime signals, created as sequence of numbers, rather than
viewed as a discretetime representation of an underlying…

This Topic uses the sampling theory developed in the previous topics to
analyse what happens when a pure sinusoid is sampled. The Topic
considers two approaches: a timedomain and a…

This Topic considers the concept of aliasing, which is signal distortion
due to the spectral overlap of the spectral images that result from the
sampling process. This Topic discusses the…

This Topic begins by discussing the mathematical model of perfect
sampling, namely multiplying the signal (that is to be sampled) by an
impulse train. Using this model, the Topic discusses how to…

This Topic introduces the concept of a sampled data system, which aims
to measure and store values from a continuoustime signal to produce a
discretetime representation. The video emphasis that…

This Topic introduces the concept of the impulse train, a sequence of
Dirac delta impulses, which can be used to perform regular sampling of a
signal. The impulse train is fundamental to Nyquist…

This Topic revisits measuring the size of a signal, but rather than
doing this in the timedomain, it is now considered in the
frequencydomain. By considering the natural size of a signal's…
