Input signal
Test circuit
Waveforms; IR = 3 mA
Input Signal - total pulse duration
- duty factor
tp(tot) = 2µs
δ = 0.0025
tr = 0.6ns
tp = 100ns
- rise time of reverse pulse
- reverse pulse duration
Oscilloscope - rise time
- cicuit capitance*
tr = 0.35ns
C < 1pF
Output signal
*C = oscilloscope input capactitance + parasitic capacitance
