Hey guys,
the question is on the attachement. I am a little stuck on part b
my answers to part a for the ABCD is
A = 1
B = 0
C = 1/Z
D = 1
and for the S parameters i have
S11 = S22 = Y/ 2 + Y
where Y, the admittance is normalised  i.e. it is Y = yZ0 = Z0/Z
S12 = S21 = 2/2+Y
anyways, moving on to part b.
I think the question wants me to show the derivation from ABCD to S parameters. i have done this for S11 and S22 which is also shown in the attachements. My question is how do i do this for S12 and S21??
I also dont know what the question is getting at when it asks for the impedance and power loss advantages and disadvantages seperately, mayb i am reading the question wrong? it isn't very well worded? I assume this refers to transduer and insertion losses which can both be calculated in terms of ABCD and S parameters??? soooo yeh no idea what this wants?
anyways, any help appreciated.
Thanks,
Lee.
