The processing of signals that are represented as a series of numbers or symbols is known as digital signal processing. A subfield of signal processing science is called digital signal processing. Analog signal processing is the other subfield of signal processing.<br />Digital signal processing (DSP) encompasses various signal processing domains such as speech and audio processing, sensor array processing, statistical signal processing, digital image processing, biomedical signal processing, seismic data processing, spectral estimation, digital image processing, digital image processing, and signal processing for communications.<br />The recording of physiological activity observations of living things, such as gene and protein sequences, heart and brain rhythms, and images of tissues and organs, is known as a biological signal. It is the clinical investigation of the body's internal metabolisms, illness diagnosis, and disease detection with the use of electronic instruments. The goal of biomedical signal processing is to take important information out of biological signals. Biomedical signal processing helps doctors track different diseases and biologists find novel biological phenomena.<br />The introduction of sophisticated electronic devices into the biomedical area led to the development of digital signal processing in this field. Numerous technologies that detected biological diagnostic data from biological creatures were invented by different scientists. Biomedical signal processing, or BMP, has allowed medical professionals to reduce their reliance on life support in a way that is both safe and beneficial. Even though these methods are well-established, the advent of new biomedical instruments has led to the continued growth of the field of biological signal processing.<br />There are many areas in the biomedical field where signal processing is used<br />1) IMAGING<br />• MRI scan,<br />• X-Ray Scans,<br />• PET- Positron Emission Tomography<br />• Electrocardiography (ECG)<br />• cellular motion tracking,<br />• laparoscopic scanning,<br />• Computerised Tomography (CT) scans,<br />• Ultra sound.<br />• Nuclear Medicine Imaging.<br /><br />2) RESEARCH<br />• Gene detection.<br />• Electronic microbial detection.<br />• Biorhythm analysis.<br /><br />3) ANALYSIS<br />• DNA analysis and comparison<br />• Biochemical synthesis analysis.<br />• RNA fingerprinting.<br />• Life Support Systems.<br />
