An electronic transmitter for a digital communication system which eliminates cumulative jitter is comprised of an input port on which a continuous input stream of data bits is received at a transmitter input bit rate. Also, the transmitter includes an output terminal on which a continuous output series of bits are transmitted, at a transmitter output bit rate that is faster than and independent of the transmitter input bit rate. This output series of bits consists of the input stream of data bits partitioned into spaced apart data blocks, with a respective output header inserted before each block. Further, the transmitter includes a digital logic circuit, coupled between the input port and the output terminal, which inserts the output headers with variable length such that a count of the number of data bits received at the transmitter input bit rate while the headers are being inserted, minus the difference between the number of data bits transmitted at the transmitter output bit rate and received at the transmitter input bit rate when the headers are not being inserted, stays within a predetermined range.
