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.

which of the above statements are correct?

Smith's chart→ The smith's chart provides a graphical representation of the impedance of the transmission line and of the corresponding reflection coefficient \((\Gamma)\) (option 1 is correct)

It is the intersection of two circles→

1) constant R-circles

2)constant x-circles 

complete circle in smith's chart i.e \(R=\infty\) to \(R=\infty\) is λ /2

360° = λ/2→ λ =720°  (option 2 is correct)

every point on the impedance Smith chart can be converted into its admittance counterpart by taking a 180° rotation (option 3 is incorrect)

clockwise movement on the chart corresponds to moving towards the generator. (option 4 is incorrect)
