Abstract
A circuit responsive to pulses on first and second input signal lines for blocking the propagation of these pulses and inhibiting the production of corresponding pulses on output lines when pulses are present at the same time on the input lines and for producing output pulses corresponding to the pulses on the input lines when there is no coincidence or concurrence of pulses on the two input lines.
Claims3
The combination comprising:
- first and second inputs each for receiving input pulses;
- first and second networks coupled to said first and second inputs, respectively, each network including a storage means set to a first state in response to the leading edge of an input pulse at its input, and each network including means responsive to the trailing edge of the input pulse and to its storage means being set to said first state for producing an output pulse at a respective output;
- and
- control means, coupled to the storage means of said first and second networks, responsive to the coincident presence of input pulses at said first and second inputs for resetting the storage means to a second state in said first and second networks and preventing the subsequent production of output pulses on the trailing edges of the input pulses.
