WebGain narrowing is produced by a finite gain bandwidth, which mainly depends on the gain material. To verify the impact of gain narrowing on the spectral shape, a theoretically calcu-lative model of CPA was designed to simulate the evolution of the Kelly sidebands in the pre-amplifier. In the CPA model, the length and core diameter of the gain ...

WebLumbar spinal stenosis is a narrowing of the spinal canal in the lower part of your back. Stenosis, which means narrowing, can cause pressure on your spinal cord or the nerves that go from your spinal cord to your muscles. Spinal stenosis can happen in any part of your spine but is most common in the lower back.
