Number of bits sent before clock drift results in error
Not what you're looking for?
Consider a frame being sent using synchronous transmission. Assume that samples are taken at the middle of the bit period and that the clocks are synchronized at the beginning of each frame (that is, there is no synchronization within the frame). The receiver clock is known to be slower than the transmitter clock; the drift is 0.02% (i.e., 0.0002). How many bits can be sent before the clock drift results in an error?

Solution Summary
Calculation is substantiated with detailed explanation of logic behind it.
Solution Preview
Let us say that bit period is B i.e. every B seconds one bit is transmitted.
Because the receiver clock is drifting by 0.02%, it will drift by (0.0002 * B) seconds with every bit.
Given that the samples are taken at the ...
