MATLAB is a software and a package to implement signal processing. Using this tool one can create and test various signals & systems. These signals and systems can be tested for various parameters and operations. The real time simulation of signals, images, audio and video are performed using MATLAB. Various programs, syntax, applications and uses of MATLAB and signal processing can be discussed in this category. As the need for signal processing is increasing day by day, there is a need for separate category.

Edge detection generally applies to a square wave signal, such as a clock pulse or a trigger pulse. Then the edge detection comes from either using the rising voltage, or the falling voltage of the signal (usually a square wave) to trigger the next event. Using the falling voltage implies a delay in…
