3Lattice phase equaliser — A lattice phase equaliser or lattice filter is an example of an all pass filter. That is, the attenuation of the filter is constant at all frequencies but the relative phase between input and output varies with frequency. The lattice filter… …

5Radar cross section — (RCS) is a measure of how detectable an object is with a radar. For example a stealth aircraft (which is designed to be undetectable) will have design features that give it a low RCS, as opposed to a passenger airliner that will have a high… …
6Time-frequency representation — A time frequency representation (TFR) is a view of a signal (taken to be a function of time) represented over both time and frequency. Time frequency analysis means analysis of a TFR. TFRs are often complex valued fields over time and frequency,… …
7Superconducting Radio Frequency — (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra low electrical loss of the superconductor yields RF resonators with extremely high quality factors, or Q . For example, it… …
8PI controller — In control engineering, a PI Controller (proportional integral controller) is a feedback controller which drives the plant to be controlled with a weighted sum of the error (difference between the output and desired set point) and the integral of …
