I am trying generate guided waves on simple metallic plate through piezo-ceramic material, I place two piezo on the surface of the plate at the different location and through Arbitrary pulse generator, I generate the Gaussian pulse of 150KHz and excite the one piezo. This excitation generate guided waves which is sensed by the other piezo. but the problem is, the output signal has very high noises and very low SNR ratio, I hardly even see the signal on the oscilloscope, but whenever I switch to the normal sine wave of the same frequency, and shut off the arbitrary and burst option, then the output signal will have very high resolution and SNR value. Please someone guide me how to reduce signal
My new method of choice is to use a variety of pass-through filters using a half-bridge rectifier diode.
