CONSTITUTION:The amplifier is constituted of a modulator 1 to convert a video signal to a high frequency, a demodulator 2 to demodulate the signal of the modulator 1 and obtain an original signal, an insulation type DC-DC converter 3 to give the power independent from other part to the modulator 1, a power device 4 and a buffer amplifier 5 to output the video signal from the demodulator 2. The device 4 supplies the power insulated from the demodulator 2 to the modulator 1 side. |
