Why signal processing

You also need to be certain your expertise will remain relevant in the technologically uncertain years to come, when AI and automation will change many of our jobs as we know it. Finally, people currently entering the workforce increasingly want to work in fields where they will be able to make a positive social impact. So, is there a way to combine all these needs and desires in one career choice? Yes, if you decide to become a signal processing engineer! Signal processing — the enabling technology for the generation, transformation, extraction and interpretation of information via electronic signals — is essential for our smartphones and wearable devices, as well as the latest health care technologies, digital cameras and our digital assistants like Amazon Echo and Google Home.

The case for a career in signal processing is threefold:. The diversity, relevance and ongoing importance of signal processing makes it an ideal area to study and pursue as a vocation. And just imagine being able to say, in an increasingly digital world, that you - quite literally - make everything possible. Signal Processing in Home Assistants. Multimedia Forensics. Careers in Signal Processing. Under the Radar. A not-for-profit organization, IEEE is the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity.

Skip to main content. This analog signal is then converted to a digital signal by an analog-to-digital converter and passed to the DSP. During the playback phase, the file is taken from memory, decoded by the DSP and then converted back to an analog signal through the digital-to-analog converter so it can be output through the speaker system.

In a more complex example, the DSP would perform other functions such as volume control, equalization and user interface. A DSP's information can be used by a computer to control such things as security, telephone, home theater systems, and video compression. Signals may be compressed so that they can be transmitted quickly and more efficiently from one place to another e.

Signals may also be enhanced or manipulated to improve their quality or provide information that is not sensed by humans e. The omnipresence of digital cameras and screens in our daily lives, such as in our smartphones, cars, drones, surveillance systems, airplanes, hospitals, and our living room, translates our ever growing need to see, share and interact with our visual environment, with increasing levels of detail. In medicine almost all diagnosis nowadays involve some sort of imaging.

However, this rapidly emerging part of the iceberg hides an important number of lesser-known, but highly essential applications, notably in the cultural, military, health and scientific research domains. Signal processing is key to a wide range of applications, from acquisition to display:.

Here are number of pointers to applications and courses showcasing image processing across various domains:. The wearables market is emerging and already thriving. Technology and sensors built into clothing and accessories track fitness levels, heart rates, physical location GPS , sleep patterns and more. Signal processing helps collect this information and translate it into useful data to be leveraged in myriad ways — such as reporting heart rate to your doctor or upping your workout routine to lose weight.

Companies utilize this data to extract information, learn about behaviors and create solutions to make our lives more efficient. Neuroscience and medicine relies on machine learning tools mixing imaging date with medical records and genomic to better understand and phenotype degenerative processes and diseases, predict responses to treatment, and cluster patients into subgroups, for example.

Signal processing. Like signal processing, data science touches our daily lives in more ways than we think. For more information on data science and its applications, visit :. Have you ever thought about communicating with extraterrestrial beings? Signal processing is integral in searching for life beyond Earth.

An important aspect to effective communications across satellite, video, radio and wireless systems, signal processing makes the processing and transmission of data more efficient. Signal Processing in Home Assistants. Multimedia Forensics. Careers in Signal Processing. Changes, updates, customizations, and many other features are available with the implementation of DSP systems. DSP allows users to get the job done efficiently, practically, and cost effectively.
