why we are using impulse signal for analysis of any control system? Impulse signal spectrum      "In signal processing, the impulse response, or impulse response function, of a dynamic system is its output when presented with a brief input signal, called an impulse". 

How Multiplexing of signals in Fiber Optical cable is done? The data transmission properties of optical fiber are well known and settle on it the media of decision for rapid information and feature  applications. In any case, different manifestations of multiplexing are obliged to exploit this data transfer capacity. Time division and 

Dense wavelength division multiplexing  (DWDM)             " The emergence of DWDM is one of the most recent and important phenomena in the development of fiber optic transmission technology. In the following discussion we briefly trace the stages of fiber optic technology and the place of DWDM in that development. We then examine the functions and components of a DWDM system, including the enabling technologies, and conclude with a high-level description of the operation of a DWDM system".

Basics of Multiplexing Defination of Multiplexing Multiplexer and Demultiplexer:      " In information transfers and workstation systems, multiplexing (otherwise called muxing) is a procedure where various simple message signs or advanced information streams are joined together into one indicator over an imparted medium. The point is to impart a costly asset. Case in point, in information transfers, a few telephone calls may be exchanged utilizing one wire. It began in telegraphy, and is currently broadly connected in correspondences". 

  Difference in FDM and synchronus TDM and statistical TDM:   In the realm of telecommunications and data transmission, the efficient utilization of bandwidth and the assurance of reliable data transfer stand as paramount objectives. To meet these goals, a variety of techniques such as Frequency Division Multiplexing (FDM), Synchronous Time Division Multiplexing (TDM), and Statistical Time Division Multiplexing (TDM) are utilized. It is imperative to grasp the unique characteristics, advantages, and applications of each method for effective implementation. Frequency Division Multiplexing (FDM): FDM is a conventional method facilitating the simultaneous transmission of multiple signals over a shared medium, such as cables or airwaves. Its principle is straightforward: dividing the available bandwidth into distinct non-overlapping frequency bands and assigning each band to a different signal. This approach allows for concurrent transmission without signal interference. Strengths o
