Digikey Electronics
To most engineers, the terms "digital circuit", "digital system" and "logic" are interchangeable in the context of digital circuits. Most digital circuits use a binary system with two voltage levels labeled "0" and "1". Often logic "0" will be a lower voltage and referred to as "Low" while logic "1" is referred to as "High". However, some systems use the reverse definition ("0" is "High") or are current based. Quite often the logic designer may reverse these definitions from one circuit to the next as he sees fit to facilitate his design. Electronic did not promote Raise the Pressure with a tour, although they performed its singles live on television shows including Top of the Pops and TFI Friday. This was to be a reaction to the length of time they spent producing Raise the Pressure, with an emphasis on writing and demoing songs quickly before recording them. Marr and Sumne
