an encoder is used to convert the binary signals into analog signals. the binary signals are fed to encoder section. then these signals are get converted into its equivalent analog signals.
Binary DAC.
Analog Modulation
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
I'm not sure if you are speaking of a specific instance.... However, a digital signal is a binary representation of the analog signal. The analog signal is constantly measured and the amplitude (voltage at the time of sample) of the analog signal is converted to a binary number at specific intervals (the frequency of the sample rate). The higher the frequency of the sample rate, the more accurate the representation of the analog signal.
Transmission Media
It's a device that samples an analog signal and outputs an equivalent binary value
Digital signal is moreefficientimmune to noiseerror freethan analog signal.
The set top box that your provider gives you is what converts the Digital signal to the analog signal. The digital signal is compressed at the provider and sent to the end user. The "tuner" (which can be built into a tv, a set top box or a cable card) Then decompresses the digital signal and converts it into an analog signal. There is much more to this did not know how technical you wanted your answer.
You sample the signal to get a number, base that number in binary, and store it. Do it often.
MOdulate/DEModulate. It converts digital computer signals into analog ones for transmission over analog telephone lines, and then converts the signal back into digital on the other end.
