WebI am programming on an embedded microcontroller (TMS320F28069) a 32-bit floating point MCU. I was going over some of the example projects, and one of them implements a simple FIR filter on ADC sampled data. Block diagram here. Let's say the ADC buffer has 10 elements. And let's say the filter has length 3 (FILTER_LEN=3). WebIt is a bit like the fable of the tortoise and the hare. The FIR filter is like the tortoise in the race – slow and steady, and always finishes. The hare is like the IIR filter – very fast, but … WebWindow, specified as a vector.
