The time-dependent pressure and flow rate are measured downstream of an artificial heart valve situated within an experimental mock circulation of the human body.

The signals are sampled at a rate of 160 Hz.

The valve opens and closes with the heart rate at 75 beat per minute.

Blocks of data are recorded at 128 samples per block.

What is the frequency resolution of the sampled data? How many signal (heart beat) cycles are included in each block of 128 samples?

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
