### Continuous to Discrete Sampling

The Continuous-Discrete Sampling Demo shows the continuous and discrete spectra and signals during sampling.
Do This:
1. Adjust the input frequency $$f_0$$. What happens when it reaches half the sampling rate, $$f_s$$?
2. Continue to increase the input frequency $$f_0$$. What happens to the output frequency when the input increates from $$f_s/2$$ to $$f_s$$?
3. What happens to the output frequency when the input increases from $$f_s$$ to $$3/2 f_s$$?
4. Based on what you have seen, what do you think will happen with the input increases from $$3/2 f_s$$ to $$2f_ss$$?
