In mmWave studio, If I set the 'Sample rate (ksps)' is 5000, it means 5M points are sampled per second. At the same time, if I set the 'ADC samples' is 256, it means 256 points are sampled per chirp. Also, I set 'No of Frames' as 160, 'No of Chirp Loops' as 255 and 'Periodicity (ms)' as 50.
In theory, if I use the formula 'Number of collected samples = No of Frames * No of Chirp Loops * ADC samples' to calculate, I should get 10,485,760 samples. But if I use the formula 'Number of collected samples = Sample rate * No of Frames * Periodicity' to calculate, I should get 40,000,000 samples.
But in fact, the number of collected samples is 10,444,800 (which means these samples contain 159.375 frames).
So my questions are:
(1) How should we calculate the number of collected samples? By using 'Number of collected samples = No of Frames * No of Chirp Loops * ADC samples', or by using 'Number of collected samples = Sample rate * No of Frames * Periodicity'. And why do these two methods get different results of number of collected samples?
(2) Why is there a difference between the number of collected samples and the calculated number of samples?
Thanks in advance!
