Digital signal processing
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The signals processed in this manner are typically represented as a sequence of numbers that correspond to samples of a continuous variable in a domain such as time, space, or frequency.
Overview[edit | edit source]
Digital signal processing and analog signal processing are subfields of signal processing. DSP includes subfields like audio signal processing, speech processing, radar signal processing, sensor array processing, spectral estimation, statistical signal processing, digital image processing, signal compression, and video processing.
Applications[edit | edit source]
DSP is used in a wide range of applications, including:
- Audio signal processing for audio compression and enhancement.
- Speech processing for speech recognition and synthesis.
- Image processing for image enhancement and compression.
- Radar signal processing for target detection and tracking.
- Telecommunications for data compression, error detection, and correction.
- Biomedical signal processing for medical imaging and diagnostics.
Techniques[edit | edit source]
Some common techniques used in DSP include:
- Fourier transform and Fast Fourier transform (FFT)
- Digital filter design, including Finite impulse response (FIR) and Infinite impulse response (IIR) filters
- Wavelet transform
- Adaptive filtering
- Multirate signal processing
Hardware[edit | edit source]
DSP can be implemented on various hardware platforms, including:
- General-purpose microprocessors
- Digital signal processors (DSP chips)
- Field-programmable gate arrays (FPGAs)
- Application-specific integrated circuits (ASICs)
Software[edit | edit source]
There are several software tools and libraries available for DSP, including:
- MATLAB
- GNU Octave
- LabVIEW
- SciPy (Python library)
