A serial data signal is received by a serial data interface (16) of a transmitter (12) and is divided equally by a divider module (230) into a preselected number, N, of signals, N matching the number of frequencies generated by a set of frequency generators (74, 76, 78, 80, 82) whose outputs feed N switches (54, 56, 58, 60, 62). The data signals are stored in N registers (30, 32, 34, 36, 38). The data is pulsed simultaneously to the control inputs of the switches (54, 56, 58, 60, 62) and turns the frequencies on and off. The resulting signals are transmitted simultaneously, then received at a receiver. The signals are applied to N bandpass filters, whose outputs are passed to N buffers and then to N switches. The N switch outputs are sent to N registers. The register contents are converted, in sequence, into a serial data signal.
