ENGR 251
Introduction to Signal Processing
Long Island University · UGRD · Fall 2026
Catalog description
Digital Signal Processing (DSP) is concerned with the representation, transformation and manipulation of signals on a computer. After half a century advances, DSP has become an important field, and has penetrated a wide range of application systems, such as consumer electronics, digital communications, medical imaging and so on. With the dramatic increase of the processing capability of signal processing microprocessors, it is the expectation that the importance and role of DSP is to accelerate and expand. Discrete-Time Signal Processing is a general term including DSP as a special case. This course will introduce the basic concepts and techniques for processing discrete- time signal on a computer. By the end of this course, the students should be able to understand the most important principles in DSP. The course emphasizes understanding and implementations of theoretical concepts, methods and algorithms. Three credits; two-hour lecture and two-hour laboratory. Prerequisites: ENGR 240, ENGR 241, MTH 100 or 19, and MTH 102 or 9
