Question: are: (Problem 1) – Three 1st-order FIR systems are cascaded together. Their frequency responses Hej@)=1+e-je H, (eje) = 1-je-jê Hz (eje) = 1-ejeje A. Write the difference equation that gives the overall relationship between the input and the output of the cascaded system. B. What is the cascaded system's impulse response? C.

Question: (Problem 1) - Three 1st-order FIR systems are cascaded together. Their frequency responses are: H(eje) = 1 + eje H, (ej“) = 1 -ejeje Hz (ejé) = 1 -e-jos A. Write the difference equation that gives the overall relationship between the input and the output of the cascaded system. B. What is the cascaded system's impulse response? C.
