AB  - FM broadcasting (as originally conceived) is capable of producing very high quality audio performance. Unfortunately, stereo transmissions degrade the signal-to-noise ratio by more than 20 dB. Under noisy reception conditions, this results in demodulated signals which do not compare favorably with other home entertainment sources. It is shown that the use of Dolby B-type noise reduction in FM transmission allows the signal-to-noise ratio to be improved significantly. Experimental results are presented, and a brief outline is given of the results of full-time broadcasting in New York.
