Abstract

The transistorized detector is used in asynchronous systems in which binary information is represented by a positive pulse for a 1 and negative pulse for a 0. The detector provides a unipolar output for each bit of information.

A One Zero & Blank Detector

The transistorized detector is used in asynchronous systems in which binary information is represented by a positive pulse for a 1 and negative pulse for a 0. The detector provides a unipolar output for each bit of information.

NPN and PNP transistors T1 and T2, having base electrodes 10 and 12, collector electrodes 14 and 16 and emitter electrodes 18 and 20, respectively, are provided. Their base electrodes 10 and 12 receive the input signals. An output is taken across a resistor R connected to the emitter 20 of T2 through a capacitor C and to the collector 14 of T1.
