Abstract
A continuous subcarrier signal generated by a voltage-controlled oscillator is supplied to a harmonic removal filter, where harmonic components contained in the continuous subcarrier signal are removed. The continuous subcarrier signal, whose harmonic components are removed, is supplied to a tint circuit connected to a variable resistor for varying the phase, where it is phase-controlled. The phase-controlled continuous carrier signal is supplied to a subcarrier amplifier, where it is applied with a predetermined processing, and a plurality of continuous carrier signals, whose phases are related in a predetermined manner, are generated.
