What is the best way to create a LOW NOISE differentiator? I am using it for a controller.
One Idea I came up with was to use a negative feedback integrator to differentiate, but the transfer function still remains the same as a regular differentiator. I was wondering what were the effects of this?
The System transfer function is
SRC/SRC+1 Where R and C correspond to the integrators components.
for those of you who dont know, the top amplifier is a summing amplifier and the bottom one is the integrator.
