Then we moved the measuring microphone 1/2-inch to the side, off center from the sweet spot, and recorded another frequency-response curve. The green curve in Figure 1 shows the first comb ...

A FILTER which passes the entire frequency range except for a set of very narrow BANDs, spaced usually at equal distances (on either a linear or logarithmic scale). The roll-off at each of these ...

Optical frequency combs, generated by means of self-referenced and stabilized mode-locked lasers, have enabled revolutionary progress in precision optical frequency synthesis and metrology 1,2,3,4.

The basic function of the video decoder is to accept analogue video from a wide variety of sources such as broadcast, DVD players, cameras and video cassette recorders, in either NTSC or PAL format ...
