Now that we’ve introduced a JK flip-flop, let’s look at some circuits that we can create using it as the core element, including the T and D flip-flops. In my previous column, we started to look at ...

In previous columns we’ve looked at TTL and CMOS logic devices in isolation. Things start to become interesting if we wish to use TTL and CMOS components in the same circuit. In previous columns we’ve ...

Part 2 mostly covers how to get real-time stock and dividend data. Readers learn how to import dividend history data and use that for stock analysis with three different approaches. We design a ...

This series will gradually develop a fully functioning Google Sheet to track and model stock performance and dividends. Part 1 covers the expected output and features of that tool and generates the ...
