Reduction in cost of hardware 3. There are many advantages and disadvantages to using digital communication systems. Disadvantages of Analog System: High cost of signal conversion inside the display. Digital is faster than analog because digital data can be stored on a computer and read in a fraction of the time it would take to store analog data. This article throws some light on IP Phones (vs) Analog/ Digital phones. It has the ability to display slow changes easily. Also, analog systems are very sensitive to interference from other equipment, storms and damage to wiring. The occurrence of cross-talk is very rare in digital communication. Disadvantages In some cases, digital circuits use more energy than analog circuits to accomplish the same tasks, thus producing more heat which increases the complexity of the circuits such as the inclusion of heat sinks. Very high accuracy for mass flow measurements. Finally, these systems can be expensive and difficult to expand when additional areas require surveillance. The detection of digital signals requires the communications system to be synchronized. It is easier, cheaper, and faster as it can be done over large distances via the internet and other things. The data and information stored or retrieved in a digital communication system can be achieved in any format like audio or video, etc. Advantages of Analog System: Uses less bandwidth More accurate Flexibility with bandwidth. They are widely used in Instrumentation, Electronics and Communication Systems especially in Signal and Image processing systems. It is Easier in processing. Main advantages: More efficient workflow as the images are available immediately on the computer A monitor in the room instantly displays the image, which allows for repositioning of patients if necessary and therefore leads to fewer retakes The digital detector provides crisps images, even of larger breast Disadvantages: The required bandwidth is increased due to digital technology. But there are some advantages for switching to a digital signal. There are many lower end, low resolution IP cameras that are low in cost. Analog signal's prime advantage is the infinite data that they have. Analog Signal Uses of Analog systems. Inconvenient and slow. The cost of the Analog wire is high and not easily portable.
