Analog and Digital Technology 2
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.
Advantages and Disadvantages of Common Modulation Techniques
Amplitude Modulation
Analogsignals have four modulation techniques. The most simple of the four is
Amplitude Modulation (AM). AM transmits data by varying the intensity of the waves. The
most common use for AM is transmitting radio stations. AM is very simple by design
