Digital technology is largely replacing analog technology because of its ability to separate the signal from the noise. This has been discussed with examples in a previous post. What we haven’t explored is what about digital technology makes this possible. To illustrate this, we will use a phone-to-phone conversation for perspective. When you speak through a phone, those waves are an analog signal picked up by a microphone. From there, the analog signal goes through an analog-to-digital converter, also known as an ADC. The ADC converts the signals into numbers based on how many electrons are passing through at a particular time. The signal then passes through a digital-to-analog converter (DAC), which turns the signal back to analog to be picked up by the receiving speaker.
At times, it can be difficult to differentiate between close numbers. The solution to this is the invention of binary code, a system of counting using 1s and 0s. Each binary digit is known as a bit, and eight bits make up a byte. These bits are created using micro transistors, which function as on and off switches to represent 1s and 0s. A digital amplifier is used to clarify the digital signal, especially when the numbers appear very similar. Without the digital amplifier, we wouldn’t be able to have a computer, let alone the internet.
