Aliasing is a phenomenon that can occur when a signal is sampled at a rate that is too low. This can result in the signal being distorted or misrepresented, as the sampled data points do not accurately reflect the original signal. There are a number of techniques that can be used to avoid aliasing, including:
Oversampling: Oversampling involves sampling the signal at a rate that is higher than the Nyquist rate, which is the minimum sampling rate required to avoid aliasing. This ensures that the sampled data points accurately represent the original signal.
