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

Acetic acid  /əˈsiːtɪk/, systematically named  ethanoic acid  /ˌɛθəˈnoʊɪk/, is a colourless liquid  organic compound  with the  chemical formula  ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called  glacial acetic acid.  vinegar  is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to  polyvinyl acetate  and  cellulose acetate. it is classified as a  weak acid  since it only partially  dissociates  in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7  3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366  chemblchembl539  chemspider171  drugbankdb03166  echa infocard100.000.528ec number200-580-7e numbere260  (preservatives)gmelin reference1380iuphar/bps1058keggd00010  meshacetic+acidpubchem  cid176rtecs numberaf1225000uniiq40q9n063p  un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4)  key:   qtbsbxvteameqo-uhfffaoysa-n  smilescc(o)=o
