FM composite generator
I want a device that takes two audio signals, left and right, and
generates the L+R and L-R signals to the FM specs in use in FM broadcasting, that I can use with a conventional FM signal generator like a HP 8640B, 8657A or a service monitor for FM stereo decoder testing. Is one still commercially available, or is one easily built such that it can be calibrated with reasonable ease? |

There's loads of schematics on the web for these, just Google for 'stereo encoder schematic' and you'll get over 68,000 results. Dave |
