Radio frequency (RF) and microwave filters represent a class of electronic filter, designed to operate on signals in the megahertz to gigahertz frequency ranges (medium frequency to extremely high frequency).This frequency range is the range used by most broadcast radio, television, wireless communication (cellphones, Wi-Fi, etc. . Below is an example of an coupled-line filter. The filter is fed with input signal through a coaxial line connector. According to the curve, a small microstrip bandpass filter with 6.67% relative bandwidth in L-band is designed by Multi-zigzag line and capacitive loading. Filter Design By the Image Parameter Method Z i1 = input impedance at port 1 when port 2 is terminated with Z i2. This reflected the radio receiver application of filtering as Q was a measure of the frequency selectivity of a tuning circuit. Since we are now dealing with mi- crowave frequencies above 0.5 GHz, LibriVox is a hope, an experiment, and a question: can the net harness a bunch of volunteers to help bring books in the public domain to life through podcasting?
