Hi,

I have this problem about signal that I have a little trouble to finish:

I attached a small figure of the circuit.

I have a High pass filter, and the equation is:

the solution for the equation is:

This is what I found and it matches with the answer from the professor.

But the question said:

Find the solution of the ODE to obtain y[t] as some integral ofx[t].

Now I need to take away the and replace by .

What i did is to use the integration by part to the solution .

I got:

My problem is that by intergrating, even though I took away what I wanted, I have introduced the variablet. I dont know if it is a problem.

My second question is the following:

Find the impulse response function so that the solution is has the form:

Hint: if you find a lonely x(t), remenber that:

Here I am confused with the boundaries of the integration

Please can I have some help with the problem

Thank you
