Functional programming (FP) is a programming paradigm that emphasizes the use of functions to solve problems. FP avoids mutable state and side effects, which can make code more predictable and easier to reason about. Popular functional programming languages include Haskell, Lisp, and Scala. Send us a message A digital signal processor (DSP) is a specialized microprocessor designed for processing digital signals. DSPs are used in applications such as audio and video processing, telecommunications, and control systems. They can perform complex mathematical operations quickly and accurately.
