Supposing I have a network filter of 3 RC filters connected in cascade configuration producing the filter H(w).
The single RC filter has a frequency response H_{RC}(w)
Is it correct the following?
H(w) = 3*H_{RC}(w)
My doubt comes from the fact that the first and second filters when connected to form the cascade, exhibit a dependency from the network following them (the rest of the cascade).
Thanks in advance R
