In a positive-logic circuit, which level is used to represent a logic 0?

Positive logic uses a high voltage to represent a logic 1 and a low voltage to represent a logic 0. So, the level used to represent a logic 0 is the low level (near 0 volts in most logic families). The exact voltages depend on the technology (TTL, CMOS), but the principle stays: high equals 1, low equals 0. The terms like positive-transition level or negative-transition level describe switching thresholds, not the static encoding of 0.
