Analog and Digital Technology: A Comparison

Analog to digital conversions techniques begin with the transmission of the information without reproduction of the original information minus the degradation with signal distortion or noise by the binary signal.  T. T. (2011).  “The binary signal consists of two values characterized by binary digits or bits 1 and 0. Unless the noise and distortion is picked up during transmission then the binary signal will not change. The value is measure by the receiver so that the reception is clear. If the information to be transferred is already in binary form as in data communications there isn’t any need for the signal to be encoded. Voice communication thru the method of the telephone is not in binary form. These signals vary in range of values are analog and within the digital communications system analog signals must be converted to digital form.”

Digital to Analog conversions involve a conversion process with DAC. This devise takes the binary code converting it to the analog signal. Digital to analog signals can compromise the quality of the signal, if it is not actively monitored. Analog lines, which are also known as POTS lines usually support standard phone lines, fax machines or alarm lines, keeping them separate from the digital PBX equipment. An example of digital to an analog signal would be the use of a modem for Internet use that converts computer digital signals using POTS lines.
