Digital signal processing (DSP) engineers establish, maintain, and alter digital signals for reliability and accuracy, often for things such as video, audio, pressure, and temperature. Analyses of these digital signals are often necessary to determine consistency and areas of improvement, and these engineers may also develop software for hardware, such as microprocessors and controllers.
DSP engineers create digital signal-processing algorithms using programs such as MatLab, Python, and GNU Octave to exploit and analyze digital signals. Complex protocols must be parsed and decoded regularly, and debugging using tools such as spectrum/logic analyzers and scopes may also be necessary, so strong problem-solving and troubleshooting skills are important in this position, as is the ability to multitask while working independently. Projects often need to be coordinated with others in the department, and DSP engineers may also work with low-level APIs, hardware interface code, and embedded software and interrupts, so a high level of technical experience in digital signal processing is necessary for this position.
It's important for DSP engineers to stay up-to-date with all new developments in this rapidly-changing field, and a strong interest in researching and creating new technologies is often emphasized. A bachelor's degree or higher in electrical or computer engineering or a related field is generally required for this position, and this is usually a full time-office job which takes place during daytime hours.
