Emissions produced by series of electrocytes, with either low voltage: weakly electric fish, or considerably high voltage: strong discharges. The duration of a single pulse varies, depending on the species, between 200 µsec to 3-5 msec. There are pulse dischargers as the Mormyridae and wave discharges (in Africa only Gymnarchus ).
