what is the difference between analog and digital systems? Digital as well as Analog System, both are used to transmit signals from one place to another like audio/video. Digital system uses binary f... ormat as 0 and 1 whereas analog system uses electronic pulses with varing magnitude to send data. Following are some of the important differences between Digital System and Analog System. . Sr. No. Key Digital System Analog System 1 Signal Type Digital System uses discrete signals as on/off representing binary format. Off is 0, On is 1. Analog System uses continous signals with varying magnitude. 2 Wave Type Digital System uses square waves. Analog system uses sine waves. 3 Technology Digital system first transform the analog waves to limited set of numbers and then record them as digital square waves. Analog systems records the physical waveforms as they are originally generated. 4 Transmission Digital transmission is easy and can be made noise proof with no loss at all. Analog systems are affected badly by noise during transmission. 5 Flexibility Digital system hardware can be easily modulated as per the requirements. Analog system's hardwares are not flexible. 6 Bandwidth Digital transmission needs more bandwidth to carry same information. Analog tranmission requires less bandwidth. 7 Memory Digital data is stored in form of bits. Analog data is stored in form of waveform signals. 8 Power requirement Digital system needs low power as compare to its analog counterpart. Analog systems consume more power than digital systems. 9 Best suited for Digital system are good for computing and digital electronics. Analog systems are good for audio/video recordings. 10 Cost Digital system are costly. Analog systems are cheap. 11 Example Digital system are: Computer, CD, DVD. Analog systems are: Analog electronics, voice radio using AM frequency. [Show More]
