How many samples would be required to see one complete period? 100Hz signal sampled 10 times at 500Hz yields how many samples per period? 100Hz = .01s period 500Hz sample rate = .002s between samples 10 samples yields .02s or two periods with 5 samples per period Add an Amplitude and Level Measurements Express VI to Exercise 2-5 How should your block diagrams be laid out?
