Cellular phones and networks
Cellular phones and networks What is Signal? A signal is an electromagnetic or electrical current that is used for carrying data from one system or network to another. The signal is a function that conveys information about a phenomenon. Analog signal is a continuous signal in which one time-varying quantity represents another time-based variable. These kinds of signals work with physical values and natural phenomena such as earthquakes, frequency, volcano, speed of wind, weight, lighting, etc. What is a Digital Signal? A digital signal is a signal that is used to represent data as a sequence of separate values at any point in time. It can only take on one of a fixed number of values. This type of signal represents a real number within a constant range of values. Now, let’s learn some key differences between Digital and Analog signals. Characteristics OF Analog Signal Here, are essential characteristics of Analog Signal These type of electronic signals are time-varying Minimum and ma
