i want a matlap code to plots this signals showen below for case (a) only i want every steps C/D up sampling and Down the solution of thre plots in every steps in case (a) is showen below i need the code that plots these steps Q. 1 The frequency representation of a continuous signal

`x(t)`

is: The input signal

`x(t)`

is passed through the system shown below. Plot the frequency representation of the output

`Y(e^(j\omega ))`

in the following cases: a)

`T_(1)=(1)/(5)sec`

,

`T_(2)=(1)/(20)sec`

,

`\omega _(c)=(\pi )/(2)`

`L=2`

,

`M=3,c[n]=cos(0.2\pi n)`

b)

`T_(1)=(1)/(10)sec`

,

`T_(2)=(1)/(40)sec`

,

`\omega _(c)=(\pi )/(2)`

`L=1`

,

`M=3,c[n]=e^(j0.2\pi n)`

c)

`T_(1)=(1)/(10)sec`

,

`T_(2)=(1)/(40)sec`

,

`\omega _(c)=(\pi )/(2)`

`L=1,M=3,c[n]=e^(j(\pi )/(2)n)`
