DRV8308EVM: 3 phase BLDC Motor- Back EMF measurement

Part Number: DRV8308EVM
Other Parts Discussed in Thread: DRV8308, DRV832X

Hi Team, We need to measure the Back EMF of the 8 pole, 3-phase BLDC Motor. We have the DRV8308EVM board and would like to measure the Back EMF of the Motor. Kindly let me know what are the best means/circuit to find it. I have attached the phase output waveform of 120 degree standard Trapezoidal and 180 degree Sinusoidal commutation of the Motor.

Motor Supply voltage: 24V
