What is aliasing? What causes it and what is the cure for it?
Aliasing is an effect that causes different signals to become indistinguishable each other during sampling process. Sampling is a process which a continuous time signal is reduced into a discrete time signal.
Sampling theorem states that " A continuous time signal can be represented in its samples and can be recovered back when sampling frequency is greater than or equal to the twice the highest frequency component of the message signal & it can be mathematically represented as
