Constant-amplitude wave combination type amplifier.
摘要
<p>A constant-amplitude wave combination type amplifier comprises variable frequency generating means 441 for generating a first constant-amplitude wave A having a controllable frequency. First wave combining means combine an input wave and said first constant-amplitude wave and generate a second constant-amplitude wave. Second wave combining means combine the first and second amplified constant-amplitude wave and generate an output wave. Control means 447 are provided for generating a control signal for said variable frequency generating means 441 from said input wave and said output wave. <IMAGE></p>
