SCHALTUNGSANORDNUNG ZUR ANSTEUERUNG EINER LICHTEMITTIERENDEN DIODE.

摘要

The input signal for the l.e.d (1) is applied to an amplifier (61). This is followed by a two-way switch (62) that diverts the signal through one of two temp. compensating circuits (64,65) corresp. to the rising and falling pulse flanks of different slopes. The switch is controlled by a differentiator (63) that detects the rising or falling edge. The differentiator also determines the min. slope at which switching is to occur.
