WebWideband photonic links suffer not only from the traditional intermodulation distortions (IMD) but also from the cross modulation distortions (XMD) caused by the out-of-band signals, which severely limit the dynamic range of the links. In this paper, we propose and experimentally demonstrate a novel scheme to effectively suppress the cross … WebIntermodulation distortion is defined as the production of new output signals which are created from the nonlinear combination of two or more input signals. This intermodulation occurs because of the nonlinearity in the amplification process.
WebAug 1, 1998 · The effect of intensity distortion induced by cross-phase modulation in dispersive optical fibers is studied. It is shown that, in most configurations in which distortions that are due to cross-phase modulation can become significant to optical communications, the effect of cross-phase modulation can be described with excellent … WebCross-Modulation Distortion Testing. The cross-modulation test serves recording engineers very much as the light meter serves photographers. That is, it helps them determine the proper light exposure to be used when producing a photographic image. The photographer judges the quality of the photograph by viewing it.
WebHammarlund SP-600 JX-17 problem. I have a JX-17 where I did the audio mods which involved doubling the coupling cap values and a cap across the 6V6 cathode resistor and the AGC mod to make it like the JX-7/10 which all worked good. The problem is that on the .54-1.34MHz band there's very slight distortion in the audio. WebJun 16, 2000 · Cross modulation distortion in CDMA receivers.
