This article according to pulse power\'s request of LSWEDM,has used singlechip and the programmable logical component(CPLD)superiority,realizes that the pulse width and clearance adjust continuously,at the same time,the high frequency pulse standard signal can achieve the ns level.

Experiment of correlation detection of weak laser pulse signals;

Portable pulse signal apparatus based on single-chip microprocessor

Research of waveform design based on UWB pulse signal

When the running situation of a rotating machine becomes abnormal or a part of it does not work well,it usually generates a periodic vibration signal or a periodic acoustic signal,which generally are periodic impulse signals with relatively strong noise.

The time domain electric field integral equation (TD-EFIE) in conjunction with the reciprocity principle is applied to synthesize the transmitting impulse signals on condition that the receiving signals have already been known.

The paper introduces a designed time domain antenna which can make the measuring electromagnetic impulse signal not distorted.
