Question

Here are the commonly used Baud rate: 2400,4800,9600,19200,38400, 115200, 460800 There is an inertial measurement unit (IMU) measurement sensor that needs to update 98 bytes data (with extra 2 label bytes) every 10 ms (100Hz), what is the minimum requirement of the baud rate? (1 byte = 8 bits) Which of the above listed Baud rate you can choose to use? (please list all of them) .

Answer 1

115200 and 460800

Step-by-step explanation:

which of the above listed Baud rate can you choose from

Given Baud rate : 2400,4800,9600,19200,38400, 115200, 460800

The Total bytes = 98 data bytes + 2 extra label bytes for every 10 ms

= 100 bytes for every 10 ms

hence the data rate per second

=
`(100 * 8)/(10*10^(-3) )` = 80000

minimum required Baud rate = 80000

Therefore The Baud rate that can be chosen from are : 115200 and 460800
