Analog and Digital Comparison
The improvements in technology have impacted people’s everyday lives immensely. Particularly, in the manner those individuals communicate. Telecommunications has seen a vast change over the years that can date back to when the telegraph was invented by Samuel F.B. Morse in 1832. In order for there to be successful communication two specifications must be fulfilled. First is the transmitter and receiver must understand each other. The second requirement is the ...view middle of the document...

Digital transmission on the other hand, is a lot easier to comprehend. The signals are made up of pulses that embody one bits and zero bits known as the binary system (Goleniewski
& Jarret, 2007). Voice or image signals are converted into numbers pre-transmission. The ones and zeros can be sent through either electrical or optical networks. Digital signals in electrical networks generate one bits as high voltage and zero bits as low voltage (Goleniewski & Jarret, 2007). Digital signals in optical networks generate one bits by the existence of light and zero bits by the absence of light (Goleniewski & Jarret, 2007). The receiver of the signals figures out what the bits represent. Also digital signals can be regenerated as they move along a network. Unlike analog signals, digital signals eliminate noise and enhance the error rate. Digital transmission offers high bandwidth that supports high-speed data.
Analog transmissions can be converted into digital transmissions and vice versa. Those conversions are made possible by codecs and modems. Codecs combine analog-to-digital conversion and digital-to-analog conversion. Some codecs are able to reduce the amount of bits per second that is needed for voice to be transmitted digitally. Compression is needed when converting cell phone networks and video communications because of the limited spectrum and channels (Goleniewski & Jarret, 2007). A modem modulates analog signals to encode digital data and demodulates the signal to decode the information sent. They can work with computers to transform the digital data into electrical signals through a telephone channel and then demodulate the signals back into digital data. However, conversions can cause malfunctions in the network so it is best to have end-to-end digital and end-to-end optical networks.
Analog technology consists of amplitude modulation, frequency modulation, phase modulation, and Quadrature Amplitude Modulation (QAM). There advantages and disadvantages to each one. Advantages to amplitude modulation include simplicity to...
