Figure 1a performs upsampling by M, followed by two M-tap boxcar filters. Figure 1b replaces each boxcar filter with an equivalent implementation consisting of a comb and integrator. The comb sections each have a delay of M samples. farberware countertop mixer colors

In mathematics, a boxcar function is any function which is zero over the entire real line except for a single interval where it is equal to a constant, A. The boxcar function can be expressed in terms of the uniform distribution as When a boxcar function is selected as the impulse response of a filter, the result is a moving average filter.
