Summary: | To reduce waveform distortion in an amplifying device.SOLUTION: An amplifying device according to the present invention comprises a pulse signal acquisition unit, a dummy signal generation unit, a compositing unit, an amplifier, and a separation unit. The pulse signal acquisition unit acquires the desired signal, which is a pulse signal to be amplified. The dummy signal generation unit generates a dummy signal. The compositing unit composites dummy signals before and after the desired signal, and outputs a composited signal. The amplifier amplifies the composited signal, and outputs an amplified composited signal. The separation unit extracts and outputs an amplified desired signal, which is a signal obtained by amplifying the desired signal, from the amplified composited signal. The power of the composited signal is the power at which the amplification unit operates nonlinearly. The power of the composited signal is constant in the time range obtained by adding a predetermined time to the time when the desired signal is present.SELECTED DRAWING: Figure 6
【課題】増幅装置において、波形の歪みを低減する。【解決手段】本発明の増幅装置は、パルス信号取得部、ダミー信号生成部、合成部、増幅器、分離部を備える。パルス信号取得部は、増幅対象のパルス信号である所望信号を取得する。ダミー信号生成部は、ダミー信号を生成する。合成部は、所望信号の前後にダミー信号を合成し、合成信号を出力する。増幅器は、合成信号を増幅し、増幅合成信号を出力する。分離部は、増幅合成信号から所望信号が増幅された信号である増幅所望信号を取り出し、出力する。なお、合成信号のパワーは、増幅部が非線形動作するパワーである。また、所望信号が存在する時間に、あらかじめ定めた時間を付加した時間の範囲は、合成信号のパワーが一定である。【選択図】図6 |
