Lowpass sampling of analog signals: (a) spectrum of analog bandlimited signal, (b) spectrum of discrete-time sampled analog signal scaled by F s and replicated, (c) aliased spectrum of discrete-time ...

Understanding what aliasing is in analog to digital conversions and why it occurs when the sampling frequency is too low.

A study of signals and linear systems and their applications in modern engineering. Representation of continuous and discrete time signals and systems in the time and frequency domains. Stability, ...

Aliasing, In Theory The Nyquist-Shannon sampling theorem states that, when sampling a signal at discrete intervals, the sampling frequency must be greater than twice the highest frequency of the ...

The difference between digital and analog signals may seem straightforward, but there is a ton of nuance that defines the characteristics of the two systems.

And understanding aliasing is the first step toward really understanding sampling, and that’s the first step into the big wide world of digital signal processing.
