Abstract
A capacitor coupling usually delays response, especially during intermittent energization that provides a battery saving feature. The invention provides a feedback which retains charges stored on the capacitor during battery saving power off intervals and which gives an almost instantaneous response when power returns. An electronic switch in the feedback path controls the charge retention.
