RE: Here's A More Direct Source

Sorry, it does. I've designed and built such encoders long before whatever internet article you maybe read existed! It is done with an analog multiplexer (switch), a 38kHz square wave source, and a div/2 ff and some phase shift networks to get the synchronized 19kHz pilot tone. If you can find a block diagram of the old National Semiconductor PLL FM stereo decoder chips you'll see the decoding done in the (reversed) same way.
