Dshot vs. oneshot and multishot:
Dshot is completely digital signal, oneshot and multishot are analog signals. During the use of analog signals, ESC hardware and software will generate some noise, which is clutter. If there are too many clutter, you need to add a filter capacitor or resistor to hardware filtering. (Off-topic, those who need to remove the capacitor is probably the case) and Dshot is a digital signal, do not need to calibrate the ESC, no filtering is required during the transmission! After all, 0 is 0, 1 is 1, no distortion and no confusion; and it is very safe with a cyclic redundancy check bit (CRC).
