Dedicated digital synthesizers frequently have the advantage of onboard accessibility, with switchable front panel controls to peruse their functions, whereas software synthesizers trump their dedicated counterparts with their additional functionality, against the handicap of a mouse-driven control system.

DSP includes subfields like: audio and speech signal processing, sonar and radar signal processing, sensor array processing, spectral estimation, statistical signal processing, digital image processing, signal processing for communications, control of systems, biomedical signal processing, seismic data processing, etc.

Today there are additional technologies used for digital signal processing including more powerful general purpose microprocessors, field-programmable gate arrays ( FPGAs ), digital signal controllers ( mostly for industrial apps such as motor control ), and stream processors, among others.

Specific examples are speech compression and transmission in digital mobile phones, room correction of sound in hi-fi and sound reinforcement applications, weather forecasting, economic forecasting, seismic data processing, analysis and control of industrial processes, medical imaging such as CAT scans and MRI, MP3 compression, computer graphics, image manipulation, hi-fi loudspeaker crossovers and equalization, and audio effects for use with electric guitar amplifiers.

Final Scratch debuted at the BE Developer Conference, marking the first digital DJ system to allow DJs control of MP3 files through special time-coded vinyl records or CDs.

Signal Processing is a very mathematically oriented and intensive area forming the core of digital signal processing and it is rapidly expanding with new applications in every field of electrical engineering such as communications, control, radar, TV / Audio / Video engineering, power electronics and bio-medical engineering as many already existing analog systems are replaced with their digital counterparts.

DSP processor ICs are found in every type of modern electronic systems and products including, SDTV | HDTV sets, radios and mobile communication devices, Hi-Fi audio equipments, Dolby noise reduction algorithms, GSM mobile phones, mp3 multimedia players, camcorders and digital cameras, automobile control systems, noise cancelling headphones, digital spectrum analyzers, intelligent missile guidance, radar, GPS based cruise control systems and all kinds of image processing, video processing, audio processing and speech processing systems.

Computers, electronic clocks, and programmable logic controllers ( used to control industrial processes ) are constructed of digital circuits.

The digital control introduces additional distortion called quantization error caused by its conversion of the input signal to a digital value.

Rackmounts are controlled by knobs or switches on their front panel, and often by a MIDI digital control interface.

However a comparable performing digital system is more complex and can require more bandwidth than its analog counterpart.

An audio file format is a file format for storing digital audio data on a computer system.

Many dual system television receivers, equipped to receive both analog transmissions and digital transmissions have analog tuner ( television ) receiving capability and must use a television antenna.

To combat this, they included a digital signature protection method which prevented unauthorized 7800 games from being played on the system.

When a cartridge was inserted into the system, the 7800 BIOS included code which would generate a digital signature of the cartridge ROM and compare it to the signature stored on the cartridge.

The lack of awareness of the system, the lack of understanding of the hardware, and fears about the digital signature lockout initially caused concerns.

Minsk has a digital metropolitan network ; waiting lists for telephones are long ; fixed line penetration is improving although rural areas continue to be undeserved ; intercity-Belarus has developed fibre-optic backbone system presently serving at least 13 major cities ( 1998 ); Belarus's fibre optics form synchronous digital hierarchy rings through other countries ' systems ; an inadequate analogue system remains operational.
