धन पश्चप्रदाय

पश्चप्रदायाची रचना खाली दर्शविली आहे.

5f958fd06802efcb2887b9c5 16471771399831

\(Gain = \frac{{{X_o}}}{{{X_i}}} = \frac{A}{{1 - A\beta }}\)

  • धन पश्चप्रदायामध्ये, वर्धन वाढते आणि बँडविड्थ कमी होते.
  • धन पश्चप्रदायामध्ये, त्रुटी देखील भिन्न होते.
  • त्याला "रीजनरेटिव्ह परिपथ" असेही म्हणतात.
