WebThe pulse-echo method - general remarks It is essential in the evaluation of a reflector that one has scanned for it and detected it (1). The procedure can be divided into the following steps: A reflector is detected. A simple evaluation can be made of the pulse echo characteristics, for example, the transit time or the maximum echo amplitude. helmet manufacturer in cleveland ohioWebreflected pulse. By comparing it to the expected length, the circuit can determine if another magnetic field has caused the reflected pulse to take longer to decay. If the decay of the reflected pulse takes more than a few microseconds longer than normal, there is probably a metal object interfering with it. helmet manufacturer in bangalore
