What is the center frequency of this filter (in hz)? note, this can be solved without finding the cutoff fre-quencies, just think about what needs to happen at resonance (it’s similar to two bpfs points)find the a-parameters by hand.(15 points)now split the circuit into four separate blocks (two-port networks containing one component each) andfind the a-parameters for each. hint: do it for a generic impedance or admittance to see the trend.(20 points)create a matlab code that calculates the a-parameter matrices as a function of frequency from 1 to 3.5 ghz. then cascade them at each point in frequency. finally, assume that the filter is terminated by a 50ωload and isexcited by a source with a 50ωsource load. the voltage transfer function is: h(ω) =v2vgfind the transfer function and plot it in db versus frequency.(20 points)remember the db scale represents power, so you need to use20 log(h).what is the maximum amplitude? explain why the amplitude is what it is.(10 points)1
