PURPOSE:The three kinds of the carrier frequency are selected to 48 X m, 48 X (m-1) and 48 X (m-2) K Hz respectively, and 48 X m is set to an integral multiple to 120K Hz to be used for the carrier wave for the first-stage modulator. As a result, a small-size and a low power driving can be realized for the unit. |
