Digital signal processing is the technique used to analyze various digital signals and obtain information from the same. It is also used to transfer information from one place to another and involves conversion between analog and digital signals. It finds its application in various areas ranging from broadcasting to medicine. Let us have a look at some of the applications of the same. Biomedical Applications DSP is used extensively in the field of biomedicine. In it, the various signals generated by the different organs in the human body are measured to find information regarding the health of the same. For example, in the case of electrocardiograms, the electric signals generated by the heart are measured. Similarly, the activity of the brain is monitored by electroencephalograms. Automatic Control These days, many gadgets are available that can perform their tasks automatically. These devices contain various components that can take inputs depending on the surrounding conditions. These are conveyed to the device’s control unit, where they are processed, and the necessary action is taken. For example, a device like a thermostat increases its resistance in proportion to temperature. This can be used to stem the current in a machine whenever the temperature rises.
