For a reciprocal transmission line, the three transmission parameters are given by A = 4, B = 7 and C = 5. The value of D is equal to
Since the transmission line is reciprocal, therefore,
The real part of the propagation constant shows:
In a transmission line terminated by characteristic impedance, Z_{0}
When a transmission line is terminated by an impedance Z, then reflection coefficient are:
Here, Z_{0} = Characteristic impedance of transmission line.
Since Z = Z_{0} therefore reflection coefficient of voltage (p_{v}) and current (p_{I}) both will be zero, i.e there will be no reflection of incident wave.
A symmetrical twopart network have
A pure resistance, R_{L} when connected at the load end of a lossless 100 Ω line produces a VSWR of 2. The R_{L} would be
The reflection coefficient of a transmission line with a shortcircuited load is
For a shortcircuited load,
reflection coefficient of voltage
and reflection coefficient of current,
Here, only option (b) matches the answer
'The characteristic impedance Z_{0} of a transmission line is given by (where R, L, G, C are the unit length parameters)
The characteristic impedance (Z_{0}) of a transmission line is given by
The standing wave ratio (VSWR) in terms of reflection coefficient ρ is given by
If a transmission line of length less than λ/4 is short circuited, it behaves as
A line becomes distortionless
A distortionless transmission line is one in which the attenuation constant α is independent of frequency while the phase.constant β is linearly dependent on frequency.
