 You may, e.g.
 - Use [`ExponentialFilter`](@ref) to add exponential filtering using `y(k) ~ (1-a)y(k-1) + a*u(k)`, where `a` is the filter coefficient and `u` is the signal to be filtered.
 No discrete-time filter components are available yet. You may, e.g.
-- Add moving average filtering using [`MovingAverageFilter`](@ref) according to `y(k) ~ 1/N * sum(u(k-i) for i=0:N-1)`, where `N` is the number of samples to average over.
+- Use [`MovingAverageFilter`](@ref) to add moving average filtering according to `y(k) ~ 1/N * sum(u(k-i) for i=0:N-1)`, where `N` is the number of samples to average over.
 
 ## Colored noise
 Colored noise can be achieved by filtering white noise through a filter with the desired spectrum. No components are available for this yet.

 Please note: this implementation of a moving average filter is not optimized for very large number of filter taps `N`.
