Homework Statement
Show that
[tex]\sum_{k=0}^{N-1}e^{\gamma \tau k}\int_{0}^{\tau}F'(k\tau+s)ds[/tex]
can be written as
[tex]\int_{0}^{t}e^{\gamma t'}F'(t')dt'[/tex]
Homework Equations
1. [itex]t=N\tau[/itex]
2. [itex]\int_{0}^{\tau}F'(k\tau+s)ds[/itex] has the same statistical properties for each interval of length [itex]\tau[/itex], and is statistically independent with respect to [itex]k[/itex].
The Attempt at a Solution
I barely know where to start. As a first step, I'm thinking that perhaps "same statistical properties" means that the integral is the same regardless of [itex]k[/itex], so that
[tex]\int_{0}^{\tau}F'(k\tau+s)ds=\int_{0}^{\tau}F'(s)ds,[/tex]
i.e., [itex]k=0[/itex]. Is this correct?
