摘要： An electronic transmitter transmits multiple digital input signals simultaneously by including an encoding circuit, a digital combiner circuit, and a modulator circuit. The encoding circuit encodes each of the digital input signals as a sequence of "1" and "0" chips with all of the chip sequences being synchronized in parallel; the digital combiner circuit generates a signed multi-bit digital signal which indicates the number of "1" chips minus the number of "0" chips that concurrently occur in the synchronized chip sequences; and, the modulator circuit generates a sinusoidal analog signal with a phase and a peak amplitude that respectively indicate the sign and magnitude of the signed multi-bit digital signal.
