Analog. They re-interpret physical movements to digital signals.
Digital signals are measured in bits per second (bps).
digital signals have two values. 0 and 1.
A microphone converts voice sound waves into electrical signals, which are then digitized by an analog-to-digital converter (ADC) to produce digital signals. These digital signals can then be processed and transmitted digitally.
Analogue signals are more vulnerable to error than digital signals. See the related question "Why digital signals are more noise free than analogue signals?" for more details.
Digital signals are measured in bits per second (bps).
To measure time between digital signals.
modem is the device that carries digital signals
Discrete time signals are sequences of values or samples that are defined at distinct intervals. Examples include digital audio signals, where sound is sampled at regular time intervals, and digital images, which consist of pixel values sampled at specific grid points. Other examples include time-series data like stock prices recorded at hourly intervals or temperature readings taken daily. Each of these signals is represented as a series of discrete points rather than a continuous waveform.

Communications signals represented in a binary format include digital signals, which encode information as sequences of bits (0s and 1s). This binary representation is fundamental in digital communications, allowing for efficient data transmission and error detection. Common examples include computer data, digital audio, and video signals, as well as protocols like TCP/IP used in networking. The binary format enables compatibility across various digital devices and systems.
