Using a spectrum-analyzer and the APD measurement equipment which was newly developed by EMC lab., the time histories of 1 sec APD were measured. For the measurement points, 2 kinds of area were selected, one of which was at the side of a road with heavy traffic and the other was in our University campus where it was very quiet, especially in the midnight through the early morning.
