real-time analyser (part 2) - base board and display board
real-time analyser elektor april 1984 ,. Last month we started this real-time analyser project and described the printed circuit boards for the input amplifier and filters. This month we have a couple of bigger boards, the base board, which serves as a mother board for all the others, and the display board containing the complete read-out section (LEDs plus electronics). With these two boards the analyser is effectively finished, except for one or two refinements. real-time analyser base board and display board (part 2) The two sections we will describe in this article are not only physically large, they are also very important within the total concept of the real-time analyser. As we spent a lot of last months"s article describ- ing the layout of the project, we will skip it this time and just get on with the technical side of the two boards. The base board For once, it will probably be easier to understand this circuit if we first look at the printed circuit board and then exam-...
