1. Consider a digital LVTTL signal from your pedalbox to your main control unit. The length / of the cable inbetween is 5m. Your motor controllers introduce a noise of 0.15 V per meter cable. To correct for that noise, you introduce 74LVC1G34, non-inverting buffers into the cable.
The purpose of the buffer is to take a signal, to which a certain amount of noise has been added so that it would no longer meet the input specification of the static discipline, and clean it up so that it once again meets the output specification of the static discipline.
