| 摘要 |
A signal transmission method which reduces the frequency band of a transmission channel by sampling the input signal, quantizing each sampled pulse, combining the quantized pulses into a group of pulses, combining the quantized pulses in each group into a single pulse the quantized amplitude of which is uniquely determined from the quantized amplitude of each component pulse. The signal transmission method is used for transmitting video, facsimile, audio, data or other similar signals characterized by a high density of information with sufficient recognizability at a comparatively slight cost of signal-noise ratio. |
