Paragraph Index: 3096

b) a 30 Hz amplitude modulation component: 1) for the conventional VOR, this component results from a rotating field pattern, the phase of which varies with azimuth, and is termed the “variable phase”; 2) for the Doppler VOR, this component, of constant phase with relation to azimuth and constant amplitude, is radiated omnidirectionally and is termed the “reference phase”. 3.3.5.2 The depth of modulation of the radio frequency carrier due to the subcarrier of 9 960 Hz shall be within the limits of 28 per cent and 32 per cent. 3.3.5.3 The depth of modulation of the radio frequency carrier due to the 30 Hz or 9 960 Hz signals, as observed at any angle of elevation up to 5 degrees, shall be within the limits of 28 to 32 per cent. 3.3.5.4 The variable and reference phase modulation frequencies shall be 30 Hz within plus or minus 1 per cent. 3.3.5.5 The subcarrier modulation mid-frequency shall be 9 960 Hz within plus or minus 1 per cent. 3.3.5.6
