Özet

Dirac delta functions are introduced to students of signal processing in their sophomore year. Quite understandably, Dirac delta functions, which should be more aptly called generalized functions or distributions, cannot be comprehensively given to a young audience at the beginning of their engineering education. Instead, a simplified and abridged definition is presented, and the implications of the definition in signal processing problems are illustrated through numerous examples, following the footsteps of Oppenheim et al. [1], [2].
