PROGRAMMABLE APPARATUS FOR SYNTHESIZED FILTER NOTCH

摘要

Generally discussed herein are systems, apparatuses, and methods for generating a replica of a first signal with a notch at one or more desired frequencies. In an example, an apparatus can include a pulse cataloger configured to analyze the first signal and to provide phase modulation information about the first signal, a direct digital synthesizer having an output and configured to modulate a second signal using the phase modulation information and to provide the second signal at the output. The second signal can include a representation of the first signal with a frequency notch at a particular center frequency within the bandwidth of the second signal.

1. A signal processor configured to receive first signal information and provide second signal information based on the first signal information, the signal processor comprising:
a pulse cataloger configured to analyze the first signal and to provide phase modulation information about the first signal; a direct digital synthesizer having an output and configured to modulate a second signal using the phase modulation information and to provide the second signal at the output; and wherein the second signal includes a representation of the first signal with a frequency notch at a particular center frequency within the bandwidth of the second signal.
