An ADC, or Analog-to-Digital Converter, is an electronic device that converts analog signals, which are continuous in nature, into digital signals, which are discrete. This conversion allows analog data, such as audio or sensor readings, to be processed by digital systems like computers and microcontrollers. ADCs are essential in various applications, including telecommunications, audio processing, and instrumentation, enabling better data manipulation and analysis in digital formats.
To pick up digital signals on an analog scanner, you can use a technique called "digital decoding." This involves connecting the scanner to a digital signal decoder or a computer with appropriate software that can interpret the digital signal formats, such as P25 or DMR. Additionally, using a discriminator output can help extract the audio from the digital signal, allowing you to listen to the transmission. However, keep in mind that not all digital signals can be decoded this way, and some may require specific equipment or software.

Digital receivers are electronic devices that decode and process digital signals, converting them into usable formats for audio, video, or data output. They are commonly used in various applications, including television broadcasting, satellite communications, and radio. These receivers often include features such as error correction, signal enhancement, and compatibility with various digital formats, enabling clear and high-quality reception. Examples include digital TV tuners, satellite receivers, and digital radio receivers.
digital signals have two values. 0 and 1.
Digital signals are measured in bits per second (bps).
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.
