"Artificial Intelligence in Diagnostics".

Artificial intelligence has been around for over 60 years. In reality it covers various techniques. One of them, Expert Systems (or Knowledge-based Systems) was introduced in the 1980s, and by the start of the next decade was in significant use in many domains. We look at some practical engineering applications, mainly in diagnosing faults.

9 Nov 2022: David Stockton GM4ZNX - Limiting Factors in Receiver Design over the Decades

Details: Written by Alan GM3PSP

9 Nov 22 - David Stockton GM4ZNX: "Limiting factors in Receiver Design over the decades".

David writes: It’s quite simple if unusual. All the marketing departments of all the component, system etc manufacturers trumpet what their products CAN do. So let’s turn that on its head and talk about what things CANNOT do. The limitations of available technologies and parts act to steer progress in ways that can make clearer than the capabilities. It’s a sort of DeMorgan’s theorem shifted outside the world of Boolean variables. But it’s a good mental trick to make complicated-looking things look more obvious, or look worse. It’s worth trying just for those cases where it pays off.
