Solution SG 27
What is the current into an R-C network when the input is a ramp with a constant slew rate?
(a) i(t) = (vin/R)*exp(-t/(R*C))
(b) current resulting from a unit step * s * t
(c) ...
(b) current resulting from a unit step * s * t
(c) ...
We know from basic electronics that C dv/dt = i. Given that the input is a ramp we know that dv/dt is a constant. Therefore the input current is a constant C*s.
