PAL
1. Abbrev. for programmable array logic. A form of PLA in whose sum of products the products (AND operations) are programmable, but the sums (OR operations) are either fixed, or programmable only to a limited extent. In the latter case, any product terms that can take part in a programmable sum are called shareable P terms.

2. Abbrev. for phase alternate line television system. The PAL standard has vertical resolution of 625 horizontal lines in two interlaced fields, which are displayed at 50 fields per second. One full frame is made of two interlaced fields, and is displayed about every 1/25 of a second. The system is very similar to the NTSC system but the frequency is modified to suit the European mains supply. To overcome a problem with the earlier system, which is susceptible to phase errors in the color signals, the PAL system alters the phase of the color subcarrier by 180° on alternate lines, averaging out the errors.
