Digital signals use binary code to represent data with two fixed voltage values, enabling clear transmission and noise removal.
A digital signal is characterized by switching between two fixed voltage values, typically represented as ones and zeroes, known as binary code. Digital signals allow for clearer data transmission when the signal is weak and can be regenerated to remove noise, making copies of copies more reliable. For example, cell phone conversations and television transmissions are commonly transmitted as digital data using binary code.
