O. Shimbo, and W. L. Cook, in the COMSAT Technical Review. 3 Shimbo et al. provide a computational method to estimate the undesired interference caused by intermodulation products of angle-modulated ...

Let’s take an amplifier and feed it with two test signals of identical amplitude, but of two different frequencies which we will call “f1” and “f2”. Since the amplifier is non-ideal, there will be ...

Unless you are a hermit or a Stylite, robust interaction with your neighbors is usually a good thing. Of course, this is not the case with broadcast transmitters, where living in isolation is usually ...

Two unique, real-world cases of interference in the FM band will be discussed by David Maxson, owner of Isotrope LLC, on the Tuesday afternoon of the upcoming Broadcast Engineering Conference at the ...

Readers of this column know that while the FCC still does not recognize interference to DTV reception caused by pairs of strong undesired (U) DTV signals, such interference is real. DTV signals on Chs ...

Charles W. Rhodes Last month, we discussed third-order intermodulation (IM3) products seldom covered in the technical literature: 2Fa + Fb, and 2Fb + Fa. We started with spectrum plots for two ...
