TECHNICAL FIELD The present invention relates to a pulse generator, and in particular, by adding a logic unit including a simple change switch to the hardware structure of a conventional bi-polar pulse generator, selectively bi-polar or uni-polar (uni) It relates to a monopolar and bipolar pulse generator capable of generating a pulse signal of -polar).;A constituent means for forming a monopole and bipolar pulse generator of the present invention includes a drive signal pattern generator for generating four different predetermined pulses having a delay time from each other, and a pulse signal generated by the drive signal pattern generator. And a pulse signal output unit for outputting a pulse signal of a single pole or a positive pole using four pulses output from the logic unit as an input signal.;Unipolar, Bipolar, Pulse, Generator
