Analog-to-Digital and Digital-to-Analog Conversions
Telecommunications relies on the transmission of data through different mediums such as a telephone, radio, television, among others. These transmissions are done through two signal types, which are analog and digital. Analog is the first type of transmission type because it is the older and has been around for a lot longer than digital. On the other hand, even though digital transmission is a younger generation, it is currently use in more devices than analog. Each signal has its advantages and disadvantages, but in most scenarios, both need to work together to create an effective transmission. Technologies that convert analog into digital and vice-versa have been created for this purpose. Converting the signals allows for a more cohesive environment because each can be adjusted to work on devices or mediums not made for them originally. The next part of this paper covers the technologies use to convert these signals. Analog to Digital Conversion
In order for this conversion to take place, an analog-to-digital converter (ADC) is necessary. This component is essential because it is responsible for receiving the analog signal as input and sending a digital signal as output. The ADC receives an analog signal such as sound, voice, or voltage and transforms that signal into a binary output. This output is the digital signal that has a state of either on, which is represented by 1 or an off state represented by 0. ADC is used in more occasions than people think. For example, whenever music is transmitted through the radio, the signal is sent in as analog and then through ADC changed into digital. Another example is the use of phones. Voice is analog, so a conversion needs to take place at the switch to convert it into digital. Analog is an older technology that is still widely used, so it is important to know how to convert it.
