Paired-Pulse Decoders Providing Echo Suppression
Abstract
The technique of diodes mixing of signals has produced new decoder circuits for IFF interrogation systems which provide echo and spike suppression and which are more economical of tubes than previous circuits. The three new circuits discussed require equality of pulse amplitude as well as proper pulse spacing for decoding. They are free from the recovery-time defect and the pulse (railings) jamming vulnerability of RC integrating circuits, and they eliminate the spurious outputs which results from coincidence of pulse edges.
