Am I correct in concluding when I use fir_filter_fff to filter, that
because it uses its own memory space, I don’t need to use set_history
worry about boundary crossing between calls to work? Will the output of
filter behave as expected across work call boundaries if I keep passing
samples to the filter?
As an example, suppose the following:
- complete input data set to be filtered, 10 samples long: [1 2 3 4 5 6
8 9 10]
- noutput_items = 2 always
- filter is 3 taps long with values: [1/3 1/3 1/3]
for(int nn = 0; nn < noutput_items; nn++)
out[nn] = d_shape_filter->filter(&in[nn]);
Will this snippet produce what you would think should be produced, a
running average over the latest three input values?
