Signal processing Operations Technology
Signal processing is one of the few scientific fields that has a basis in applied mathematics, electrical engineering, and systems engineering. The convergence of interests with this field has been used to improve how signals are both sent and received, with the manifestations of research being found in medical devices, audio transmission techniques, and television broadcasting.
One of the most common operations of signal processing is called spectrum analysis. With this operation, a signal is monitored using a special analyzer to measure the frequency and magnitude of the signal being produced. This can be used with acoustic sounds or light waves and the analyzer can detect and graph special properties, such as harmonics and wave distortion. Another common operation of signal processing is called pattern recognition. This happens when correlating input and output signals are able to be matched, creating a pattern where classification can take place.
An example of a device that has been invented from signal processing study is the EKG (Electrocardiogram) machine. The EKG revolutionized medical prognostication with its meticulously precise and accurate readings. An EKG will tract the heart's electrical activity to reveal how fast it is beating. Also, it will let us know whether that heart is beating steadily or irregularly, and how strong the heart beatings are. With such information, doctors can predict and prevent heart attacks, and other heart disorders that can dangerously affect a patient.
Another example of how this machine could be used is in testing if a man should use certain medications, which would directly or indirectly affect the heart's performance. For instance, an EKG will reveal if a man who suffers from ED could safely use
Generic Viagra as a treatment. By recording his heart rate, a doctor can understand if any risks are present or not for that particular patient. Likewise, EKG's will let doctors know if a patient's heart could withstand aggressive surgeries or treatments such as chemotherapy, etc.
In short, Signal Processing has opened doors to medical, electrical and systems technologies so advanced that they have greatly improved and even saved the lives of millions around the world.
