Sensiiviy vs. Supply Volage IR Signal from fluorescen lamp wih low modulaion Suiable Daa Forma The circui of he is designed in ha way ha unexpeced oupu pulses due o noise or disurbance signals are avoided. A bandpass filer, an inegraor sage and an auomaic gain conrol are used o suppress such disurbances. The disinguishing mark beween daa signal and disurbance signal are carrier frequency, burs lengh and duy cycle. The daa signal should fulfill he following condiions: Carrier frequency should be close o cener frequency of he bandpass (e.g. 38 khz). Burs lengh should be 10 cycles/burs or longer. Afer each burs which is beween 10 cycles and 70 cycles a gap ime of a leas 14 cycles is necessary. For each burs which is longer han 1.8 ms a corresponding gap ime is necessary a some ime in he daa sream. This gap ime should be a leas 4 imes longer han he burs. Up o 800 shor burss per second can be received coninuously. Some examples for suiable daa forma are: NEC Code (repeiive pulse), NEC Code (repeiive daa), Toshiba Micom Forma, Sharp Code, RC5 Code, RC6 Code, R-000 Code, Sony Code. When a disurbance signal is applied o he i can sill receive he daa signal. However he sensiiviy is reduced o ha level ha no unexpeced pulses will occur. Some examples for such disurbance signals which are suppressed by he are: DC ligh (e.g. from ungsen bulb or sunligh) 1690 0 5 10 15 0 Time ( ms ) Figure 14.
