摘要

The influence of bandwidth restriction on the performance of a PCM transmission system is treated. In particular, the relationship is investigated between signal-to-noise, bandwidth, and bit-error probability of an NRZ (non-return-to-zero) signal. The detector used in the investigation contains a device that integrates the signal over the bit period. Theoretical results were obtained by a Fourier analysis of bandwidth-restricted signals and by an autocorrelation analysis of the bandwidth-restricted noise. Theoretical and experimental results are in good agreement.
