 | | In order to use an analog signal on a computer it must be digitized with an analog to digital converter (ADC). | | | Since the goal of DSP is usually to measure or filter continuous real-world analog signals, the first step is usually to convert the signal from an analog to a digital form, by using an analog to digital converter. | | | Often, the required output signal is another analog output signal, which requires a digital to analog converter. |

| | The transformation of an Analog signal to Digital information via an Analog-to-digital converter is called sampling. | | | Most digital media are based on translating analog data into digital data and vice-versa (see digital recording, digital video, television versus digital television). | | | Digital media ("Formats for presenting information" according to Wiktionary:Media) like digital audio, digital video and other digital "content" can be created, referred to and distributed via digital information processing machines. |

| | The continuous signal is usually sampled at regular intervals by an Analog to digital converter and the value of the continuous signal in that interval is represented by a discrete value. | | | The target of the signal processing is often another analog output signal which requires a digital to analog converter for translation. | | | Digital signal processors have heavily parallel architectures optimized for DSP computations and are designed to operate in real-time. |

| | The input to an analog-to-digital converter (ADC) consists of a voltage that varies among a theoretically infinite number of values. | | | Computers "talk" and "think" in terms of binary digital data; while a microprocessor can analyze analog data, it must be converted into digital form for the computer to make sense of it. | | | Digital signals propagate more efficiently than analog signals, largely because digital impulses, which are well-defined and orderly, are easier for electronic circuits to distinguish from noise, which is chaotic. |

| | Digital Television: An Overview |
| | Because DTV signals cannot be received through the existing analog television broadcasting system (known as NTSC (7)) the FCC decided to phase in DTV over a period of years, so that consumers would not have to immediately purchase new digital television sets or converters. | | | Consumers can continue to use analog TV sets until the broadcasters return the analog TV licenses to the FCC, after which, a set-top digital converter box could be used to enable the analog TV set to receive the DTV signal. | | | Accepted copyright protection technologies to "plug" the "analog hole" have not yet been developed, and will likely require further technology development and negotiation involving the content providers and consumer electronics manufacturers. |

| | The term "DAW" simply refers to a general combination of audio multitrack software and high-quality audio hardware — the latter being a specialized audio converter unit which performs some variety of both analog to digital (ADC) and digital to analog (DAC) converters. | | | A professional DAC performs the same function as a common sound card, but is generally an external and sometimes rackmounted unit which offers the advantage of far less noise (hum, static), higher recorded resolution, and better dynamic range, when compared with its consumer cousin. | | | Computer-based DAWs consist of three components: a computer, an ADC-DAC, and digital audio editor software. |

| | Digital audio signals are decoded by a digital-to-analog converter. | | | High bit-rate, high sampling-rate digital signals are capable of producing better sound quality than any analog audio format (although some people feel analog phonograph records produce purer sound than current compact discs, higher resolution digital audio signals provide the additional resolution to be a superior sound reproduction technology regardless of who is listening). | | | Digitizing an analog waveform involves breaking it up into many, many small pieces that can later be lined up together to form a close approximation of the original, continuous signal. |
