- Bit slip
digitaltransmission, Bit slip is the loss of a bitor bits, caused by variations in the respective clock rates of the transmitting and receiving devices.
One cause of bit slippage is overflow of a receive buffer that occurs when the transmitter's
clock rateexceeds that of the receiver. This causes one or more bits to be dropped for lack of storage capacity.
One way to maintain timing between transmitting and receiving devices is to employ an asynchronous protocol such as start-stop. Alternatively, bit slip can be prevented by using a
self-clocking signal(such as a signal modulated using OQPSK) or using a line codingsuch as Manchester encoding.
