please help me to understand the word transducer
transducer convert one energy to other energy .now in analog transducer it convert energy use of analog signal and digital it converts use og digital signal
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.
Analog is displayed in a clock like instrument digital is shoun in numbers
A microphone is an analogue to electrical transducer.
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.
Analog signals are continuous while digital signals are discrete
* 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.
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
