GENERATING A PSEUDO-SIGNAL IN AN ERROR RATE SUPERVISORY UNIT |
摘要 |
A method and circuit for generating a pseudo-error signal comprising a demodulator circuit for demodulating an input signal; a first discriminator circuit for regenerating a first digital data signal by discriminating the output of the demodulator circuit; a noise extracting means for extracting a noise component from the input signal; an adding circuit for adding the output of the noise extracting means and the output of the demodulator circuit; a second discriminator circuit for regenerating a second digital data signal by discriminating the output of the adding circuit, and; an exclusive OR circuit for recognizing whether or not the first digital data signal coincides with the second digital data signal. |
