Consider the following statements regarding the Smith's chart:
1. Smith's chart is a graphical indication of the impedance of a transmission line and of the corresponding reflection coefficient as one moves along the line.
2. λ distance on the line corresponds to a 720° movement on the Smith's chart.
3. The admittance chart can be obtained by shifting each and every point on the impedance chart by 90°.
4. Counter-clockwise movement on the chart corresponds to moving towards the generator.
