Abstract

The system has a device to convert the bit frequency of an input signal into (m+1)/m times that of the input signal, where m is an integer. A device inserts a bit into the bit sequence after every bit before the additionally inserted bit, where k is an integer and lying between 1 and m. The resulting sequence is the output signal. The device receives a clock signal having the same frequency as the input signal and contains a shift register, a frequency divider, an AND-gate and a flipflop. The advantage lies in simplicity and reduced likelihood of transmission error.
