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,
In a transmission line terminated by characteristic impedance, Z0
When a transmission line is terminated by an impedance Z, then reflection coefficient are:
Here, Z0 = Characteristic impedance of transmission line.
Since Z = Z0 therefore reflection co-efficient of voltage (pv) and current (pI) both will be zero, i.e there will be no reflection of incident wave.
A pure resistance, RL when connected at the load end of a loss-less 100 Ω line produces a VSWR of 2. The RL would be
The reflection coefficient of a transmission line with a short-circuited load is
For a short-circuited load,
reflection coefficient of voltage
and reflection coefficient of current,
Here, only option (b) matches the answer
'The characteristic impedance Z0 of a transmission line is given by (where R, L, G, C are the unit length parameters)
The characteristic impedance (Z0) 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.
