A certain cellular telephone antenna has an input impedance at f=1.0 GHz modeled by a shunt R-C combination, with R=200Ω and C=2.0pF. Because of manufacturing restrictions, you can only work with microstrip, and cannot use vias or wrap-around grounds, i.e. all your stubs must be open-circuited. Design a matching network that consists of balanced stubs of either 1/8 or 3/8 wavelength (choose the shortest length that will work) and a quarter-wave transformer. Sketch the microstrip network, and label the lengths and characteristic impedances of the lines. You do not need a Smith chart to do this. Your sketch should depict the equivalent source on the left and antenna (load) network on the right, with the matching network in between.
If an FM signal is given by s FM (t) = 100 cos [2πf c t +100 m(τ ) dτ ] and m(t) is given in figure, sketch the instantaneous frequency as a function of time and determine the pea
