Detects beats in EODs of wave-type weakly electric fish

Author

Jan Benda

Detects the peaks and troughs of EOD beats. The dynamic threshold is set to ratio times the amplitude of the beat and decays after a delay down to minthresh with a time constant decay.

Input

The times and amplitudes of EOD cycles.

Output

The times and amplitudes of beat peaks and troughs.

Options

• threshold=6: Threshold (number)
• minthresh=6: Minimum threshold (number)
• delay=0sec: Delay time (number)
• decay=10sec: Decay time constant (number)
• ratio=50%: Ratio threshold / size (number)
