6.2.2.1.1 definition of EFT parameters
The
Repetition , Burst Duration and Spike Frequency are combined in the number of spikes / seconds value
(Spike Rate):
Spike rate [Spikes/s] = (Burst duration [ms] / repetition [ms]) x spike frequency [kHz] x 1000
This formula is only valid if the „
Burst Duration “ is lower than the „ Repetition “. If the „ Burst Duration “ is
equal the „ Repetition “, the „Spike Rate“ will be equal to the „ Spike Frequency “ (continuous burst).
Spikes per Burst = Burst duration [ms] x Spike frequency [kHz]
