Explanation –
Digital Signals are discrete (non-continuous) in nature. They provide discrete values which can be represented in form of discrete steps. Digital Signals are transferred in binary 0s and 1s – the combination of which forms binary system. Digital Signals can however, not be represented by decimals because they have only ON (binary 1) or OFF (binary 0) states.
