Hello, nice to see as you are back with the spectrum analyser project :) Your videoshere inspired me a year ago, so I made the ADC, LOGDET, DDS, MO modules in the meantime. Strugling with PLO2 now, but hope to succeed soon. Have a good luck! Tomas
Also known as "Mickey-Mouse" logic from page 242 of Don Lancaster's CMOS Cookbook. M2L logic, "Mickey-Mouse logic should be used with discretion and only in slower portions of systems. It should never be used above 100kHz or so." Handy when you need a gate but don't want to waste a whole IC package to get the job done, but with limitations. George
