Summary
A short description of the transmitting and receiving organ of Gnathonemus petersii is followed by results of experiments carried out to measure the sensitivity of the receptors for external signals (communication) and for distortions of the own electric field (active object location) with and without additive noise. Possible principles of reception are synchronous, asynchronous and threshold receivers; further experiments indicate the threshold receiver to be the most probable structure. Treating the active object location as a problem of statistical communication theory yields for small disturbances to a generalized cross-correlator, which in this case behaves like a threshold receiver.
