Associated with Nyquist rate is the concept of aliasing. What is the significance of aliasing in the context of digital communication and what corrective measures can be used to overcome aliasing?
aliasing is an effect that causes different signals to become indistinguishable when sampled. It also refers to the distortion when the signal reconstructed from samples is different from the original continuous signal.we can't reconstruct our original signal due to this effect.
To overcame this , sampled it at the rate fs which is grater than twice the maximun frequency of two times of fmax.
fs> 2fm
