In mathematics, a leaky integrator equation is a specific differential equation, used to describe a component or system that takes the integral of an input, but gradually leaks a small amount of input over time. It appears commonly in hydraulics, electronics, and neuroscience where it can represent either a single neuron or a local population of neurons.[1] Template:Clarify
Equation
The equation is of the form
where C is the input and A is the rate of the 'leak'.
General solution
Its general solution is
where k is a constant.
