This video is part of the Texas Instruments Precision Labs – ADCs curriculum: . It introduces the concept of frequency domain aliasing and describes how aliases are error sources that we want to avoid or minimize.  It also covers how an anti-aliasing filter can be used to minimize these aliasing errors with an analog-to-digital converter (ADC).
