Errata to “demonstration of a 3‐GHZ‐bandwidth real‐time spectral‐analysis receiver based on a high‐TC superconductive chirp filter (invited paper)”

A 3-GHz-bandwidth real-time spectral-analysis receiver has been demonstrated. The fully integrated compressive receiver is based on the chirp-transform algorithm and uses a high-Tc superconductive (HTS) tapped-delay-line chirp filter with a time-bandwidth product of 40. The 3-GHz bandwidth of the HTS chirp filter is unobtainable using other technologies such as surface acoustic waves. This prototype receiver, a combination of an HTS passive microwave component and conventional semiconductor circuits, demonstrates a microwave system that could not be built without the unique HTS component. © 1993 John Wiley & Sons, Inc.
