T and Pi Pads — attenuatori resistivi

Floppy IMG derived from archived files. Mount as FLP1 and boot using Minerva 1.98a1 ROM, 640 KiB and Toolkit II 2.32. Corrected parentheses in both PI formulas. For 100/50 ohms and 10 dB, checked rounded T values 73/11/50 and PI values 438/69/101 ohms independently. No physical circuit test. Basic functional check in sQLux, not a complete test or a test on physical QL hardware. Audio not tested. ROMs are not included.
