Match List I & II and select correct answer using the code given below: 

List I (Quantity)		List II (Range of values)
a.	input impedance	1.	-1 to +1
b.	reflection co-efficient	2.	1 to ∞
c.	VSWR	3.	0 to ∞

The correct option is 3

Concept:

Input impedance typically depends on the specific device or system, it could be very low or very high, not necessarily within a specified range.

It ranges from 0 to \(\infty\).

The reflection coefficient is used to define the reflected wave with respect to the incident wave.

The reflection coefficient of the transmission line at the load is given by:

\({\rm{Γ }} = \frac{{{{\rm{Z}}_{\rm{L}}} - {Z_0}}}{{{Z_L} + {Z_0}}}\)

ZL = Load impedance

Z0 = Characteristic Impedance

It varies from -1 to +1

The voltage standing wave ratio (VSWR) is given by:

\(VSWR = \frac{{1 + |{{\rm{Γ }}_L}|}}{{1 - |{{\rm{Γ }}_L}|}}\)

For ΓL = ± 1, VSWR = ∞

For ΓL = 0, VSWR = 1

∴ VSWR ranges from 1 to ∞.
