Example Output Signals
Figure 5: Output signal for 2 µs pulse light.
Transmitter: LED 875 nm with tr = tf = 0.1 µs;
VCC = 5 V, R1 = 10 kΩ, CL = 20 pF;
Chan 1: V(OUT), 1 V/DIV vertically,
Chan 2: I(LED), 20 mA/DIV vertically
Figure 6: Output signal for 2 µs pulse light with noise
(accumulated over 256 samples)
Figure 7: Output signal for 2 µs pulse light, superim-
posed by ambient light of approx. 15000
Lux
Figure 8: As in Fig. 7, accumulated for visibility over
256 samples. Despite of bright ambient
light condition noise remains low level.
