D-MAC

Among the family of MAC or Multiplexed Analog Components systems for television broadcasting, D-MAC is a reduced bandwidth variant designed for transmission down cable.

• The data is duobinary coded with a data burst rate of 20.25Mbit/s so that 0° as well as ±90° phasors are used.
• D-MAC has a bandwidth of 8.4 MHz versus 27 MHz for C-MAC.
• Most cable systems work on EBU 7 MHz channel spacing, so this approach did not work universally.
• D-MAC's bandwidth problems were later fixed by D2-MAC.

DMAC may mean:

• Dimethylacetamide, a widely used chemical solvent
• p-dimethylaminocinnamaldehyde, a chemical and a method to evaluate the polyphenolic content of a sample
• Digital Media Arts College, a private college in Boca Raton, Florida, USA
• An abbreviation of 'Direct Memory Access Controller', a device used to perform Direct Memory Access
• disseminated mycobacterium avium-intracellulare complex (from ICD-9-CM)
• Des Moines Art Center
• Diving Medical Advisory Committee, is an independent committee, formed in 1974 to provide advice about medical and certain safety aspects of commercial diving.

Dimethylacetamide (DMA) is the organic compound with the formula CH₃C(O)N(CH₃)₂. This colorless, water-miscible, high boiling liquid is commonly used as a polar solvent in organic synthesis. DMA is miscible with most other solvents, although it is poorly soluble in aliphatic hydrocarbons.
