The electric motor does not work on the principle of the amplifier and the digital signals.
A digital converter converts the analog signals that are received by your TV to digital signals. Most TV providers only offer digital TV these days, so you only need it if you're still using analog.

Signals that represent information using a sequence of 0s and 1s are typically digital signals. These signals can be in the form of electrical voltages, light pulses, or radio waves, where specific states (high/low voltage, on/off light, or presence/absence of a wave) correspond to binary digits. Digital encoding techniques, such as pulse-code modulation or binary phase-shift keying, are often used to transmit this binary information over various communication channels.
Two forms of electrical signals are analog signals, which vary continuously over time, and digital signals, which represent data as discrete values. Analog signals can take on any value within a range, while digital signals have specific voltage levels to represent binary data.
The two basic kinds of electronic signals are analog signals and digital signals. Analog signals are continuous and can take on any value within a given range, while digital signals are discrete and represent information as a series of binary values (0s and 1s).
Modulation
The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.
The conversion of letters, sounds, and images into electrical signals is called digital encoding. This process essentially translates analog data into a digital format that can be easily transmitted and processed by electronic devices.
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.

Signal encoding is the process of converting information into a specific format for efficient transmission or storage. It involves transforming data into signals that can be easily understood by communication systems, such as electrical impulses, light signals, or digital bits. The significance of encoding lies in its ability to enhance data integrity, minimize errors during transmission, and optimize bandwidth usage, ensuring that the information reaches its destination accurately and quickly. Proper encoding is crucial for effective communication in various applications, including telecommunications, data storage, and multimedia.

A digitizer graph can be used to convert analog signals into digital signals by sampling the analog signal at regular intervals and assigning numerical values to the sampled points. These numerical values represent the amplitude of the signal at each sampled point, allowing the analog signal to be represented in a digital format that can be processed and stored by a computer or other digital device.
Digital signals are measured in bits per second (bps).
