A digitized signal is an analog signal that has been converted into digital form using sampling and quantization. This process allows devices to store, process, and transmit the signal using binary data.
For example, surveillance systems digitize video and audio signals to enable recording, streaming, and analysis. Digital signals are less prone to interference and easier to manage than analog ones.
While analog signals vary continuously, digitized signals break data into discrete values. As a result, they offer higher consistency and better integration with modern technologies.
By converting analog input into a digitized signal, systems improve quality and enable advanced features.
