a) The frequency variable f can be defined by For every fixed value of the frequency ‘F’. is periodic indeed. It can be represented.  It is the fundamental period of sinusoidal signal  So it is period with that period.

b) The frequency variable f can be defined by   So, it is non periodic.

c) The frequency variable ‘f’ can be defined by   So, it is non periodic. Because the frequency is not expressed in the ratio of two integers.

d) In this the frequency variable  can be defined by          So, the product of the It is non – periodic.

e) In this the frequency variable   can be defined by         So, so, so, So, the is period.
