Final answer:
The message is encoded in the signal by converting it into binary ones and zeros. This allows for clearer data transmission and compression of digital data. Each one or zero in the binary sequence represents one bit of data.
Step-by-step explanation:
The message is encoded in the signal by converting it into a sequence of binary ones and zeros. This encoding method is commonly used for transmitting digital data, such as cell phone conversations, television voice and video images, and computer data. Each one or zero in the binary sequence represents one bit of data.
