Sonar is like radar but uses sound waves instead of radio waves. Sound doesn’t allow for the range of radar signals, but it is a great alternative for simulating radar. With such a simulator, it is ...
Nanosecond current pulses arise from avalanche breakdown in virtually any diode. Here some experiments exploring these in Zener-diodes, LEDs and finally photon-counting avalanche photodiodes are ...
Chinese manufacturers of measuring equipment keep surprising us with affordable multifunction instruments that we would not have thought possible a few years ago. In this review, we will take a look ...
