*3:Four types of frequency :36.0, 36.7, 38.0, 40.0KHz
*2:Place major axis of elliptic lens in horizontal direction and minor vertical.
Transmitting waveform is shown in Fig.1
Transmitting power should be adjusted
so that output voltage Vout will be
400mVp-p.(Test circuit is shown in Fig.2)
Regarding IR LED used for transmitter,
Regarding photo diode,
in case light source temperature2856°K,
