| 摘要 |
Instruments are disclosed for testing the susceptibility of PCM regenerators to rear end and far end crosstalk noise. The instruments of the invention are more compatible with PCM system engineering rules since certain important PCM system parameters are synthesized in the circuitry. The instrument for measuring susceptibility to rear end crosstalk includes a filter having a voltage transfer function 1/R3¦f/fo¦3/4 and the instrument for measuring susceptibility to far end crosstalk includes a filter having a voltage transfer function 1/R3¦f/fo¦. |
