What is aliasing?


assistant
Aliasing is a signal processing phenomenon caused by trying to measure a signal with too low of a sample rate. This means that the time between consecutive measured samples (the sample rate) is too infrequent to properly capture the information of the signal. An example of this is the "carriage wheel" effect, where on film, car tires may appear to go backwards when the car is traveling forwards.
