SUITABLE DATA FORMAT The series are designed o suppress spurious oupu pulses due o noise or disurbance signals. Daa and disurbance signals can be disinguished by he devices according o carrier frequency, burs lengh and envelope duy cycle. The daa signal should be close o he band-pass cener frequency (e.g. 38 khz) and fulfill he condiions in he able below. When a daa signal is applied o he in he presence of a disurbance signal, he sensiiviy of he receiver is reduced o insure ha no spurious pulses are presen a he oupu. Some examples of disurbance signals which are suppressed are: DC ligh (e.g. from ungsen bulb or sunligh) Coninuous signals a any frequency Srongly or weakly modulaed noise from fluorescen lamps wih elecronic ballass (see figure 4 or figure 5) IR Signal 692 IR Signal from Fluorescen Lamp wih Low Modulaion 5 5 2 Time (ms) Fig. 4 - IR Signal from Fluorescen Lamp wih Low Modulaion IR Signal from Fluorescen Lamp wih High Modulaion IR Signal 692 5 2 Time (ms) Fig. 5 - IR Signal from Fluorescen Lamp wih High Modulaion TSOP348..
