The growing ion acoustic wave instability caused by the slow electron drift is studied by both CW and pulse modulatedwave methods.
用连续波和调制脉冲波两种方法研究了由慢电子漂移引起的增长离子声波不稳定性。

A power converter circuit (3) drives a switching device by the pulse-width modulatedwave for converting a direct current into the three phase alternating current.
Spectrum of the amplitude-modulatedwave is observed by a radio frequency spectrum analyzer and amplitude values of every spectrum are recorded at the upper sideband or lower sideband.
