Note 3. “Standard Stereo Multiplex Signal” here refers to a 200mVRMS (0.56VP–P) composite stereo
signal including 10% pilot with L = 1 and R = 1 as described in the FCC Rules of FM Broad-
casting.
Note 4. Measured with a stereo composite signal consisting of 80% stereo, 10% pilot and 10% SCA
as defined in the FCC Rules on FM Broadcasting.
