Hi,
This is my first post so please bear with me-
I am currently analysing an low pass filter Sallen-Key circuit.
I need to find a system response to an input step signal Vin=Vo u(t) with Vo=1V using a convolution.
Obviously its a continous time system, I have managed to derive an transfer function \(\displaystyle H(s)= \frac{1}{1+C_2(R_1+R_2)s+C_1C_2R_1R_2s^2}\)
I am assuming I should use the time invariance formula below, am I right?
could someone please explain to me how can I apply convolution theory?
\(\displaystyle y(t)=\displaystyle\sum_{k=-\infty}^\infty x(k\omega) \omega h(t-k\omega)\)
Thanks
