... under-standing concepts such as fast algorithms for digital signal processing (i.e., fast Fourier transforms, and fast convolution algorithms; e.g., see Ref. 4), cryptography and data security, and ... If x ∈ X and a ∈ K, then the product of a and x is ax,andax ∈ X.(V7) If x, y ∈ X,anda ∈ K, then a(x + y) = ax +ay.(V8) If a, b ∈ K,andx ∈ X, then (a + b)x = ax +bx.(V9) If a, b ∈ K,andx ∈ X, ... abstract than Boolean algebra, convolution integrals, and Fourier or Laplacetransforms, all of which are standard fare in present-day electrical and computer engineering curricula.Engineering past...
