# Periodic non-uniform sampling - effective bandwidth to select correct anti-aliasing filter

What is the effective bandwidth of sampling at a rate $$f_s$$ for a burst of $$N$$ samples, where the bursts are triggered at rate $$f_B$$?

For example, say $$f_s \approx$$ 10 kHz, $$N \approx$$ 1000 and $$f_B \approx$$ 5 Hz
