 | The method of claim 1, wherein the amplitude of the second order sideband and the extent of reduction of the carrier level with respect to the level of the first order sideband are substantially directly proportional to the square of the first order sideband level for all modulation levels. |
| The method of claim 10, wherein the amplitude of the second order sideband and the extent of reduction of the carrier level with respect to the level of the first order sideband are substantially directly proportional to the square of the first order sideband level for all modulation levels. |
| The means of claim 14, wherein the amplitude of the second order sideband and the extent of reduction of the carrier level with respect to the level of the first order sideband are substantially directly proportional to the square of the first order sideband level for all modulation levels. |

| A multiple signal carrier transmission apparatus and method for broadcasting stereo sounds to an audio output device uses three related carrier frequencies on which are modulated the sum of first and second stereo channel signals and the... |
| A method for generating a compatible AM quadrature stereo wave by delivering a modulated carrier with in-phase sidebands generated by a first combination of two signals, and quadrature sidebands generated by a second combination of the s... |
| The signal as transmitted is a compatible AM stereophonic signal with amplitude directly proportional to the monophonic signal 1+L+R. The instantaneous phase angle is the quadrature phase angle modified in that high level, high frequenci... |
