Hello Dr Shekhani, Your videos are AWESOME and i have learned a lot.. I am just a tinkerer and creating an ultrasonic application for a personal medical problem that currently does not have cure. i have learned so much from your videos and web page. Thank you!!!!
Thanks for all video you made, i want to ask sir, curently laboratory worker in my college working with ultrasonic circuit, this circuit used to measure propagation speed on fruit, we using 2 transducer for transmit and receive, when we use the circuit we measure signal in oscilloscope, but something weird happen and i dont understand. When measuring input signal from receiver, the osiloscope showing 2 peak which is the first one is peak when transmitter active, and second one is pulse after propagate. My laboratory worker want to get rid of first pulse, he said its not supposed to be there. But i dont really understand how, do you have any idea about this sir? Thank you 🙏

1.573 is a pretty close approximation to pi / 2. When you are dealing with frequency, this is probably is not a coincidence...
