Consider the signal x(t)=4λβ⋅sinc² (2βt)−λβ⋅sinc²(βt) where the values of the constants λ and β are

Given that b=1,c=1, d=1 λ= 10c+d+2/2 and β= 10b+c+2/2

in which b,c and d are the values from your student number.

Write down the values of λ and β in your answer script and answer the following questions using these values.

Find an expression for the spectrum, X(f), of x(t). Draw an adequately labeled sketch of X(f)
