Webb13 apr. 2024 · In this report, joint parametric and passive amplification by a factor ≈50 on GHz-bandwidth signals is demonstrated. Furthermore, it is shown that the decimation process can effectively mitigate effects of narrowband noise, outperforming traditional optical and digital filtering techniques. WebbCertain bandpass filter designs only allow for narrowband bandpasses, or high Q-factors. Others allow for much wider bandpasses, or low Q-factors. For a notch filter circuit, the …
