et a time signal be given by

$()=$ sin$(10)+$ sin$(103)+$ sin$(106)$

a$.$ Design a filter $1()$ that attenuates the frequency components at $103$ and $106$ rad$/$s and

retains the magnitude of the component at $10$ rad$/$s$.$

b$.$ Design a filter $2()$ that attenuates the frequency components at $10$ and $106$ rad$/$s and

retains the magnitude of the component at $103$ rad$/$s$.$

c$.$ Design a filter $3()$ that attenuates the frequency components at $10$ and $103$ rad$/$s and

retains the magnitude of the component at $106$ rad$/$s
