digital coommunication is a mode of communication where the information is encoded digitally as discrete signals & electronically transferred to the recipients.
analog communication format is that in which information is transmitted by modulating continuous signal, such as sound wave.

What are the disadvantages of analog communication?
Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference.
What are the Advantages of analog and digital communications?
Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference. Advantage of Analog Communication: 1)Transmission bandwidth required is less. 2)No need of synchronization. Advantage of Digital Communication: 1)Digital Communication systems are simpler and cheaper. 2)Using data encryption only permitted user are allowed to detect the transmitted data. 3)Since in Digital Communication, channel coding is used, therefore a large amount of errors may be detected 4)Since transmitted signal is digital in nature,large amount of noise tolerance may be tolerated Disadvantage of Digital Communication: 1)More transmission bandwidth required. 2)Digital Communication needs synchronization in case of synchronous modulation.
What is digital analog simulators?
Analog system simulation is more sensitive to the changes in the parameters compared to the digital system. This is because of the continuous nature of the analog signals, unlike the discreet nature of the digital signals. Digital systems have gates which can not be used in Analog system.
A device to place digital signals on an analog system and vice-versa?
DAC - Digital to Analog ConverterADC - Analog to Digital Converter
What is analog simulation?

Why the measure of performance in analog communication system is signal to noise ratio while in digital communication system is probability error?
it is mostly a matter of what is easiest to define & measure in each context.

Is baseband digital or analog?
Both, Like any other form of communication. However, all analog forms of communication/transmission will end in February of 2009. All manufactures have already changed to the digital format, therefore in a couple of months any older system will be obsolete.
What are the differences between analog system and digital system?
Analog would be like a sliderule which is based on logarithms. Digital would be like a calculator.
What is a analog-to-digital converter chip?
Its an IC which converts the analog signal at its input into digital output suitable for digital applications. It is an essential part of any digital system
What is the clock time of analog to digital converters?
The clock time of analog to digital converters depends on the design of the converter, which depends on the performance expectations for the system.
What are the advantages of analog system and digital system?
An analog system is usually simple requiring few components and gives results almost instantlyA digital system gives repeatable results with no drift or temperature sensitivity that can be as precise as desired
