PDF - Portable Document Format file. The file format in Adobe's Acrobat document exchange technology. Acrobat/PDF is a computer file format for publishing and distributing electronic documents (text, image, or multimedia) with the same layout, formatting, and font attributes as in the original. The files can be opened and viewed on any computer or operating system; however, special software is required. @a2vgear |
Peak - Highest level of signals strength. @a2vgear |
Peak-to-peak - Difference between the maximum positive and maximum negative values of an AC waveform. It is Abbreviated as "p-p." @a2vgear
