Study Notes
Digital Signal Processing (DSP)
- The primary purpose of DSP is to enhance or manipulate digital signals to extract useful information or improve their quality.
Applications of Digital Signal Processing
- Common applications of DSP include image and speech processing, biomedical signal processing, and telecommunications.
Advantages of Digital Signal Processing
- A key advantage of DSP over analog signal processing is that it allows for greater flexibility, precision, and accuracy in processing and manipulating signals.
Representation of Digital Signals
- Digital signals represent discrete-time signals in digital signal processing.
- In digital electronics, a digital signal is represented as a sequence of binary digits (bits) that can have only two distinct values, 0 and 1.
Exclusions and Subfields
- Digital signal processing is not typically applied to mechanical engineering.
- Subfields of signal processing include analog signal processing and digital signal processing.
Operations in Digital Signal Processing
- DSP can involve various operations such as filtering, amplification, modulation, and transformation to enhance or manipulate digital signals.
Generation of Digital Signals
- Digital signals in DSP are typically generated by analog-to-digital converters (ADCs) that convert continuous-time analog signals into discrete-time digital signals.
Domain of Digital Signals
- The digital signals processed in DSP represent samples of the discrete-time domain.
Parent Field of Signal Processing
- Digital signal processing and analog signal processing are subfields of signal processing.
