http://www.rctn.org/bruno/npb261/aliasing.pdf WebIn C and C++, aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++, the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule.

WebAug 20, 2015 · In signal processing field, aliasing refer to the misidentification of signal frequency. For example, due to the lack of the adequate consideration in under-sampling step it may lead to the generating errors and distortion.
