ABSTRACT:
An integrable circuit arrangement for deriving a coincidence pulse on coincidences of the falling edges of pulses of a digital data signal with the falling edges of pulses of sampling signals obtained by frequency division and gating and intended for use in a digital data processing system is disclosed which requires little area on an integrated-circuit chip. It contains an input gate consisting of a first NOR gate and a second NOR gate which are cross-coupled. The sampling signal is applied to the first input of the second NOR gate, and one of the system clock signals to the first input of the first NOR gate. The first input of a third NOR gate is connected via an inverter to the output of the first NOR gate, while the data signal is applied directly to the second input of the third NOR gate, and the delayed data signal is applied to the third input in inverted form.
