Analog means continuous transmission of data whereas digital
means discrete transmission of data. In analog
communications we are transmitting finite amount of data in
infinite amount of information. so,there is a possibility of
occurrence of noise. where as in digital we are transmitting
finite amount of data in finite amount of information. so ,
out of these two, digital is most efficient.
Analog communications need to use radio waves or air waves to communicate between a receiver and a source. Digital communications use satellites for communication between a receiver and a source.

Analog is displayed in a clock like instrument digital is shoun in numbers
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
Analog signals are continuous while digital signals are discrete

The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
Analog can reach higher speeds.

In analog ckt there is more distortion but in digital there is no distortion. Analog is a continues value digital is a discrite value(0 or 1). To measure analog is very difficult but in digital it is very easy. compare to analog the digital system is very compart for us. H.L.Kiran

Analog is a clock with the moving hands on it, while digital is computer generated numbers.

* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves. * Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
please help me to understand the word transducer
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
