السؤال بواسطة uka1024 على 2018-06-09 05:13:04
lmorelli Theknock (or "bump" ) is due to the power off-power on of the system. To avoid it you should isolate the amplifier from the power source.

سؤال: hello, did anyone manage to make it work with a ultrasonic transducer? and if yes, how
السؤال بواسطة MARIOS على 2021-01-24 04:26:47
lmorelli The kit generates waveforms with a defined amplitude. You have to match the correct amplitude, frequency, waveform and impedance of your own transductor. The kit should easily reach 100 kHz, but the waveform tends to degrade above that frequency.
