A voltage amplifier without feedback has a nominal gain of 500. The gain, however, varies in the range of 475 to 525 due to parameter variations. In order to reduce the per-unit change to 0.02, while maintaining the original gain of 500, if the feedback is introduced, find the new direct transfer gain G and the feedback factor H.
