MOTTAGARE FOR PULSFORMIGA LJUSSIGNALER

摘要

A receiver for impulse-shaped light signals, in which the time interval between successive light signals is considerably larger than the time duration of the individual light signals, and in which the interference voltages or static generated at the output of the receiver is reduced through the intermediary of a zero-point suppressor, and in which the then remaining disturbance impulses are adjusted to a particular prescribed value through a sensitivity control arrangement and/or amplifying control arrangement. The receiver includes a further, more rapid control sequence in addition to the above-mentioned control sequence, whose control voltage is obtained from the output voltages of the receiver prior to the zero-point suppression.
