Hi all, I'm using three sensor nodes (MICAz + MTS310), positioned at the same distance from a sound source, to sample a click signal at 4kHz.The sensor nodes start sampling simultaneously once they receive a start command from a base station and a buffer is used to hold 1200 samples in each sensor node. When the buffer is full, each sensor node will start sending their sampled data to the base station which will forward them to a PC. They send their own sampled data serially to the base station. When I plot the received signals I expected to get coherent signals but this was not the case although the experiments were conducted in the same environment and under the same conditions. So, what could be the reasons for such incoherent signals?
I appreciate any help in advance, Omar _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
