Consider a 1Mbps transmission channel. The clock at the receiver has a drift of 1 second in one year. How long asequence of bits (or frame) can be sent before the clock drift could cause a problem? Assume that the sender and receiver are synchronized at the beginning of each frame and that they cannot resynchronize during the frame. Also, assume that the receiver samples the received signal at the middle of each bit duration to detect if it is 0 or 1.
