The voltage is a sine wave signal of frequency 60Hz, and of amplitude 110Vrms. Draw this waveform showing period and amplitude.
1. You are measuring this waveform using a device that samples every 0.001s. Show the sampled waveform.
2. Show how the sampled waveform changes if the sampling period changes to 0.01s, 0.1s, and 1s.
3. You are measuring heart beats of a person. This person's heart rate is 100 beats per minute. Draw five heartbeats showing the period between two consecutive beats.
4. Your measurement device samples data every 0.1 minute. What is the heart rate you will measure?
5. How will your measurement change if the sampler period goes down to 0.01 minute?
6. How will your measurement change if the sampler period goes up to 1 minute?
