Use Digital Signal Processing instead of Analog Signal Processing

Prophets
“Thus, although many signal processing will be most economically implemented with analog methods, it is the capability of digital system to achieve a guaranteed accuracy and essentially perfect reproducibility that is so appealing to engineers. … To summarize, the importance of the DSP should eventually surpass that of analog signal processing for the same reasons that digital computers have surpassed analog computers.”
Digital better than Analog
Analog
- Aging
- Sensitivity to the environment
- Uncertain performance in production units
- Variation in performance of units
- Sensitivity analog traces on PCBs
- Effort to migrate and adopt “canned” solutions
Applications
Audio (sound card, digital musical instruments)
Automotive (Security Systems, Safety Systems)
Medical (Medical Imaging, Personal Medical Devices)
Military (Data Communications, Radar/Sonar)
Telecom (Navigation Systems, Telecom Accessories)
Video and imaging ( Digital Still Cameras, Digital TV)
Wireless communication (cell phone, Bluetooth Solutions)
Summary
Digital system has perfectly reproducible and never varying performance.
Applications already became everywhere, and more will come.
For any signal problems, think about digital first!
