1.	Which of the following expression is true if Z1, Z2 are same type of reactance?(a) sinhα/2cos⁡β/2=x(b) coshα/2cos⁡β/2=0(c) coshα/2sin⁡β/2=x(d) sinhα/2sin⁡β/2=0The question was asked in my homework.This is a very interesting question from Classification of Pass Band and Stop Band topic in portion Filters and Attenuators of Network Theory
Answer» CORRECT OPTION is (c) coshα/2sin⁡β/2=x The explanation is: If Z1, Z2 are same TYPE of reactance, then the imaginary PART of sinhϒ/2 = sinhα/2cos⁡β/2 + jcoshα/2sin⁡β/2 should be some VALUE. So coshα/2 sin⁡β/2=x.
